what is the mean of P in this video? I try to make my homework but the threshold voltage is 0.13. And if voltage greater than 0.13 the transmitted bit is 0. AWGN channel has 5dB SNR. I must derivate a probability function for the situation that is the transmitted bit is 0 but received bit is 1. Can anybody help me
can anyone give the matlab code for implementing the models for calculation of ber of various digital modulation techniques such as ASK, FSK, PSK, M-PSK. Also implement models to predict propagation losses for communication microwave signals
At 17:32 Q(x) EQ #0 for 10 dB SNR, SNR = 10 Pe EQ #1 At 14:42: Pe = 7.82 * 10^(-4) ------------> EQ #2 The result from EQ #1 is less than EQ #2 But according to EQ #0: Pe
Are you sure that the 1/2 coefficient in the approximation belongs there? The approximated value in the example seems to be pretty much exactly 1/2 of the exact value.
because we have to use new limits of integration when we substitute t=n/sigma. The previous limits belong to variable n so by substituting n limits of integration in the new variable t =n/sigma we get new limits as infinity and p/standard deviation.
Indian . you are the worst one who try to explain communication theory. You never concern about the quality of your lectures but view number of your videos. Actually, you are disturbing people from finding the highest quality information
YOU'RE A GREAT LECTURE, THIS FIELD IS NOT EASY BUT YOU'RE MAKING IT AWESOME FOR US
Thank you sir !! u saved my life
thanks for the lecture
Thank-you so much!
thank you sir
good explanation sirthank you very much
Sir,Your work is marvellous and magnificent
where are u working currently ??
At 17:40 1/2*e^(-5) = 3.4 * 10^(-3) ..... what am I missing?
Sir, I love you.
sir,when you are talking about average power it is whether rms power because average power of sinusoidal wave is zero

for 10 dB SNR, SNR = 10
Pe EQ #1

The result from EQ #1 is less than EQ #2
But according to EQ #0:

It's a mistake. the correct answer should be 3.37*10^(-3).
3.91*10^(-4) = 1/2 * 7.82*10^(-4). Looks like the numbers got mixed up in his notes.

You are right, the 1/2 shouldn't be there
Check the Wikipedia article. The half is there for q function approx.
at 5:40 why does the lower limit of integration becomes( p/standard deviation) instead of p... can any one make it clear please
because we have to use new limits of integration when we substitute t=n/sigma. The previous limits belong to variable n so by substituting n limits of integration in the new variable t =n/sigma we get new limits as infinity and p/standard deviation.
