A bit error probability of Pg = 10 is required for a system with data rate of 100 Kbits/s to be transmitted over
an AWGN channel using coherently detected M-PSK modulation. The system bandwidth is 50 KHz. Assume
that the system frequency transfer function is a raised cosine with a roll-off factor r = 1 and that a Gray code
is used for the symbol to bit assignment.
a) What E/ N is required for the specified Pg ?
b) What Ep /No is required?
