using Matlab to solve the following, a, consider a data sequence encoded with a (127,64) BCH code and then modulated using coherent 16-ary PSK.if the received Eb/No is 10 dB, find the MPSK probability of symbol error,the probability of code bit error ( assuming that a Gray code is used for symbol- to- bit assignment),and the probability of information -bit error. b,For the same probability of information-bit error found in part (a),determine the value of Eb/No required if the modulation in part (a) is changed to coherent orthogonal 16-ary FSK.Explain the difference.
