Publisher review:BPSK BER simulation - correlative detector for BPSK signal I need to solve the problem with BER calculation. I made a coherent correlation type detector in MATLAB for a BPSK signal, but when I demodulate the noised signal BER is much worse than it sould be in theory for coherent detection.
I add noise using awgn() function setting the desired SNR[dB]. I assume Eb/No[dB]=SNR[dB] 10log(Tbit/Tsample) So why is it? My M-files are attached. I used 1000 bits to simulate and SNR=-12dB which equals according to the equation Eb/No=8dB. Theoretically the result shoul have been around 1e-4 and I get BER=4e-2. The BER curves of the desired and of the reality I have are also enclosed.
BPSK BER simulation is a Mathematica script for Other scripts design by Bogdan Mikhailets.
It runs on following operating system: Windows / Linux / Mac OS / BSD / Solaris.
