What's the problem? In my case, I use ACPR of Spectrum Analyzer to measure the SNR of signal after channel. The SNR and Input signal power, referenced to 1 ohm (watts) of AWGN Channel Block are 20 dB and 1 watts respectively. When the power of ACPR is around 20 dB, which is equal to the SNR we set in AWGN Channel Block, the Channel Powers showed in Spectrum Analyzer is around-20 dB, which I expect to … How can we simulate the BER Vs SNR for AWGN channel using matlab coding?

function channel_simulation(BER1,BER2,Nbits) % BER1: prob 0->1 % BER2: prob 1->0 if nargin <3, Nbits = 10^6; end % Data generation mapped to BPSK signal (-1,1) r = rand(Nbits,1); x = 2*(r>=0.5)-1; % Noise (channel 1) SNRdB1 = 10*log(qfuncinv(BER1)); y1 = awgn(x,SNRdB1); y1 = 2*(abs(y1-1) is it Eb/No (average bit energy/power spectral density)? If so, then i know the awgn has a PSD equal to No/2. does that psd in the snr term implies No/2? The AWGN assumption simplified the channel model and allowed us to learn the basic skeletal operation of NOMA. function channel_simulation(BER1,BER2,Nbits) % BER1: prob 0->1 % BER2: prob 1->0 if nargin <3, Nbits = 10^6; end % Data generation mapped to BPSK signal (-1,1) r = rand(Nbits,1); x = 2*(r>=0.5)-1; % Noise (channel 1) SNRdB1 = 10*log(qfuncinv(BER1)); y1 = awgn(x,SNRdB1); y1 = 2*(abs(y1-1) Learn more about ber, modulation, qam, lte MATLAB, Communications Toolbox
out = awgn (___,powertype) specifies the signal and noise power type as 'dB' or 'linear' in addition to the input arguments in any of the previous syntaxes. For the relationships between SNR and other measures of the relative power of the noise, such as Es / N0, and Eb / N0, see AWGN Channel Noise Level. Grupp. 5 augusti 2017 ·.
