Find the probability of bit error for the coherent matched filter detection of the equally likely binary FSK signals: ( 29 ( 29 t t s t t s 2020 cos 5 . ) ( 2000 cos 5 . ) ( 2 1 = = where the two-sided AWGN power spectral density is . 0001 . 2 / = o N Assume that the symbol duration is 0.01seconds. 4. Consider a BPSK system with equally likely waveforms: ( 29 ( 29 t t s t t s o o cos ) ( cos ) ( 2 1-= = At the matched filter detector, the ) ( 1 t s reference is ) cos( + t o , where is the phase error. Calculate the value of the phase error that would increase the probability of bit error from 2.0x10 3-to 2.5x10 3-relative to no phase error for AWGN channel....
