Super cool idea! 👍

Astronomical software prices and no Linux support no use

..i had one of my board heat up and die....few years ago...im ok i moved on..learned alor though...thank for the great video.

I appreciate your work..i play with this ..and its my soon to be dream job..wow .i learned alot.thanks stay Great

I am trying to use an Analog Devices AD9082 with a Xilinx ZCU102 host board. My idea is to send data from the processor to the DAC and to receive data from the ADC and send them to the processor. Can this video help me ?

No support for BladeRF ? Ettus? every heard of soapy??? Jail for you

no polar plot???? what sort of shitty WAYDAR is this

*Improving EVM Performance with Equalization: An AD9082 MxFE Case Study* * *0:00** Introduction:* Don Metzer introduces the concept of using equalization to enhance the Error Vector Magnitude (EVM) of a communication signal using the Analog Devices AD9082 MxFE chip. * *0:39** What is Equalization?* Equalization is a technique used to compensate for imperfections in the signal path (transmitter, channel, receiver) using a finite impulse response (FIR) filter with complex-valued tap coefficients. * *1:03** Fixed vs. Adaptive Equalization:* Fixed equalization uses constant tap coefficients, while adaptive equalization continuously adjusts them for optimal performance. * *2:28** Measurement Setup:* A Xilinx ZCU102 host board with Analog Devices IO software controls an AD9082 FMCB evaluation board. An 8PSK waveform at 500 Mega symbols per second is transmitted and received via loopback. * *6:24** Initial EVM Measurement (No Equalization):* Without equalization, the EVM is measured at 3.93% (-28dB), significantly lower than the expected signal-to-noise ratio (SNR) of around 50dB. * *8:30** Adaptive Equalization Applied:* Enabling adaptive equalization with 33 complex taps dramatically improves the EVM to 0.28% (-51.2dB), close to the theoretical SNR. * *10:56** Saving and Applying Fixed Equalization:* The tap coefficients from the adaptive equalizer are saved and applied as fixed equalization, maintaining good EVM performance (around 0.3% or -51dB). * *13:49** Testing with Different Waveforms:* The effectiveness of the fixed equalization (trained on the 8PSK signal) is validated using a 64 QAM DBPSK waveform (14:35) and a 256 QAM waveform (16:46), both resulting in significant EVM improvements. * *19:29** Summary of Results:* Equalization, both adaptive and fixed, resulted in a substantial improvement of approximately 23dB in EVM performance. * *19:31** Equalization as AI:* The video highlights the concept of equalization as a form of AI, where a mathematical algorithm (complex FIR filter) is trained with data to perform a useful task (improving EVM). I used gemini-1.5-pro-exp-0801 on rocketrecap dot com to summarize the transcript. Cost (if I didn't use the free tier): $0.07 Input tokens: 17504 Output tokens: 518

It's cool but the components are too expensive

Is it equivalent to SA software ?

Is Kuiper needed for connecting with the TES software?

Great video. Thank you.

I would love to understand at least some of what this is, it sounds like it's really useful but I couldn't keep up! ;u;

Coincidentally, the owner of the house in the background is asking his wife, "does it seem warm in the house?"

Is there a gnuradio implementation of this setup available for dowhload?

*Abstract* This video demonstrates how to set up and analyze signals using an Analog Devices AD9081 FMCS EBZ evaluation board hosted by an Analog Devices ADS9 digital board running Analog Devices Ace software. The transcript covers essential steps, including network setup, configuring the Ace software, and generating waveforms. Additionally, the video demonstrates the use of the Quick Receiver Pro software to perform advanced signal analysis. This includes demodulating a 64 QAM signal and achieving excellent EVM results through adaptive equalization and zero-IF corrections. *Keywords:* * Analog Devices * AD9081 FMCS EBZ * ADS9 * Ace * Quick Receiver Pro * signal analysis * QAM * EVM * adaptive equalization i used gemini

It is a great implementation, no doubt about it, and also a kind of niche one...That being said,, 250 USD license for a MONTH? A month?! Are you out of your mind with the pricing? Like i said, it is a niche product, but it is being distributed for general use, military wings or whatever that should be sucked dry, not common people! Do not moan when people pirate your software.

hey can we communicate?

Can this system detect movement or presence of human through brick wall?

Thank you for the video, regarding the rf components, could you tell from where to got them?

where to buy the apps?

Hi, I tried to download the software but the site could not find

Hi tried to download software but page gave a 404 error

Now make a AESA radar hehe

As far as I know, many of the spinning radar dishes are just reflectors and the actual emitter and receiver antenna is mounted under them in the axis of rotation, aiming upwards to get reflected away horizontally. But for that, one would have to either interpose the rx/tx antenna somehow, or just use a single one switching between the functions corresponding to a timer.

Why not maximize the window?

Sounds like they’re talking about a Retro Encabator

There are Blog ?

I'm an old timer, but I can't understand the modern fascination with "software defined" (enter application here). Any digital system is by definition software defined, even if the "program" is hard wired by an arrangement of discrete chips, because someone had to "write" the algorithm or code (software) that makes it perform its intended purpose. Radar is nothing more than sending a short RF signal burst and measuring the return time, length of return time differences (if the radar antenna is not fixed), and phase of that signal when reflected from a distant object. Doing this can allow you to deduce approximate size, distance, and if done repeatedly, speed of an object. Modulation of the wave burst is not strictly necessary. Truly accurate radar had to wait for digital time keeping techniques, and it was implemented as soon as it was available. RF carrier signals transmitted over the air MUST BE sine waves; if not, you interfere with other users of the radio spectrum. If you want to digitally generate the base frequency, we are talking frequency synthesis (this includes RF mixing for heterodyning). Want to modulate the signal using digital techniques? Go ahead...but don't claim it is a new process. All forms of modulation are almost as old as radio itself - AM, FM, PM, packet, TDM, FSK (two tone or more), and many others. Most are done digitally at this point. Digital frequency selection has been standard on radios for many years. With "software defined" radio, you are not "defining" anything. You are merely replacing what analogue sections you can with digital processes, and making it where the end user can change key parameters of the controlling algorithm...things that have been done already. This seems much like how manufacturers advertise "digital" antennae for TV reception - a new name to stimulate interest and buying frenzies, but in reality the same thing you already have. Someone here tell me where I am wrong...what am I not seeing?

If you had, say, twelve of these, set up 30 degrees apart in a circle, and used the software to look at each one in succession and combined the output onto one readout.... would that be a homebrew phased array radar? Sounds expensive.... but still less expensive than figuring out how to create a rapidly spinning radar dish all powered up and working.

Came for the home-made radar. Stayed for Girl from Ipanema theme music.

I am going to build this and mount it on my DeLorean.

I Love Brazil

I made a crude dish reflector for a doppler microwave lamp circuit and was able to boost the range to where it saw me moving. I think it samples the return signal and hears an audio beat when the target moves near or farther away. Very cheap radar.

Nice Don! Glad to see you're still working with RF!

I had no idea that you had encoded music in your signal 6:30 7:50 I love the music though!

great job brother! what to do if we are designing monostatic radar?

great job brother! i want to know about modifications regarding ground surveillance radar. i am using adalm pluto.

Very good sound. Tom Jobim

Could you hypothetically use it to receive but with an omnidirectional receiver to filter and attenuate incoming signals?

I admit I know nothing about SDR, so what is this for ?

Should refrain from using abbreviation in the title. Software Defined Radio (SDR).

Great video. Is the matching filter implemented on the FPGA or on the software??

This is a very interesting software; I wonder why it is not popular in the maker community I followed VERY similar instruction but with a minor deviation from your excellent presentation; and actually it work. Here are the details; I hope that helps others First, I installed your APP on Ubuntu via wine (windows emulator on linux) Second, I used PlutoPlus (the Chines hacked version) and connected it via its 1 GB ethernet RJ45 port. Third, I had to choose a transmit file with lower sampling rate. Your application didn't allow me to choose a sampling rate greater than 30 MHz although the Pluto was hacked to behave as such. See Analog's documentation. They gave the instructions to hack into AD9364 and to AD9361. Fourth, I used the antennas (without the cable) and transmitted at 0 db of attenuation. Fifth, I transmitted at 830 MHz; not 1 GHz. The antennas has lower VSWR/return lose at this frequency Many thx again Cheers

this is very interesting have to try on my system, than you for inspiration

Next step - replace ADRV9361 with a half-dozen MPF-102s
