How to find frequency and phase shift in the recorded wave( .wav file )

I am working on BPSK at frequecies near 20 kHz with a sample rate of 44100 Hz. We can't afford sample rates above than this due to computational complexities. …

Periodically-varying phase between transmitted sound and received sound

phase_difference_1 = phase_shift(signal_1,signal_2) phase_difference_2 = phase_shift(signal_1[:55],signal_2[:55]) print phase_difference_1,phase_difference_2 output : 0.249981325271 0.249951020276 I am doing BPSK

why does the decision boundary change in BPSK? is it true?

I am working on modulation and demodulation of BPSK using python. i made a code for modulation and demodulation,while demodulate i tried to compare my actual data bit stream with demodulated bit stream … if so how can we find the shifted decision boundary for my BPSK. thanks in advance, any help is greatly appreciated :). …
