Unformatted text preview: 10 watts/Hz. Find the average carrier power required to maintain an average probability of error P e <104 for coherent PSK. 3. 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 twosided 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 3to 2.5x10 3relative to no phase error for AWGN channel....
