+//Given

+Rb=4.8D+3; //b/s

+bw=3.2D+3; //Hz

+

+//BPSK can give maximum spectral efficiency of 1bps/Hz, therefore not suitable

+//QPSK can give twice spectral efficiency,2bps/Hz, therefore

+qpsk=2*bw;

+//PSK can give thrice spectral efficiency,3bps/Hz, therefore

+psk=3*bw;

+//QPSK is most suitable
