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. …

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 :). …

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
