– Generate random bits using a Bernoulli Binary Generator.

% Parameters M = 2; % BPSK modulation order numBits = 1e5; % Number of bits EbNo_dB = 0:2:10; % SNR range ber = zeros(size(EbNo_dB)); for idx = 1:length(EbNo_dB) % Generate random bits data = randi([0 1], numBits, 1); Digital Communication Systems Using Matlab And Simulink

– Map each pair of bits to a complex symbol using the QPSK Modulator Baseband block. Set average power to 1. – Generate random bits using a Bernoulli Binary Generator

% Add AWGN snr = EbNo_dB(idx) + 10*log10(log2(M)); % Convert Eb/No to SNR rxSig = awgn(modSig, snr, 'measured'); % SNR range ber = zeros(size(EbNo_dB))

– Compare original bits with demodulated bits using the BER Calculator block. Export results to MATLAB workspace using an "To Workspace" block.
