Noise Variance
cpsh...@rediffmail.com - Feb 17 2008
Hi
In soft demapper, we need either value of SNR or noise variance sigma. Now in real time we do not know both of these.
And lets say that we know variance of white noise b... 
Phase determination of the harmonics
Ninad - Feb 15 2008
I was using the following file to determine the magnitude of the
harmonics. My actual signal is 60 Hz and it has harmonics, i.e.,
contains odd harmonics. The following program ca... BER for 4QAM with AWGN Channel [5 Articles]
loc truong - Feb 13 2008
hi everyone,
I am trying to simulate a OFDM system with AWGN channel, 4QAM symbol in matlab.
Theoritically, the curve for BER should be the same as for BPSK
BER = Q(sqrt(2*... Big size Matrix Problems ! [4 Articles]
