a bit error probability of pb= 10-3 is required for a system with a data rate of 100 k bits/sec to be transmiited over an awgn channel using coherently detected mpsk modulation.the system bandwidth is 50 khz. assume that the system frequency transfer function of a raised cosine with a roll factor r=1 and a gray code is used for the signal to bit assignment.

a) what Es/No is required for the specified Pb?

b)wat Eb/No is required?

Hint: Note that the symbol error probability in coherent MPSK is

Pe= 2Q [ ( square root 2Es/No) sin(pi/M)

where Es = (log2m)Eb

Suppose a full-scale voice signal with bandwidth 10 kHz is sampled at the Nyquist rate and quantized by using a b-bit uniform quantizer. The bit stream is then transmitted using binary PAM over an AWGN channel that is capable of passing frequencies in the range of [0, 200kHz]. 1. Suppose that the signal is transmitted at the maximum bit rate and the two-sided spectral density of noise at the receiver is 10-6 W/Hz. What is the required signal power to...
