Regards Sir,

can u give me the matlab code for the BER compersion of conventional BPSK, QPSK and 8PSK over an AWGN channel.

Regards

With higher order modulations, for the same data rate, we can have longer symbol durations there by reducing the bandwidth. Please lookinto the section Bandwidth requirements and Capacity in the article in dspdesignline.com http://www.dspdesignline.com/howto/208801783;jsessionid=BWJIYHNJDMGCPQE1GHOSKH4ATMY32JVN?pgno=2 @batman: If the symbol duration is T, the minimum bandwidth required (with sinc shaped pulse shaping) is 1/T (from -1/2T to 1/2T).
