WebThe expected bit rate for BPSK can be calculated. Assuming a baud rate of 4800, the following bit rate is achieved: C = Rlog2(M) C = 4800 log2(2) C = 4800 bps The bit rate for QPSK with a baud rate of 4800 is as follows: C = Rlog2(M) C = 4800 log2(4) C = 9600 bps QPSKs data rate is double that of BPSK, while using the same amount of bandwidth. http://edge.rit.edu/edge/P09141/public/FSK.pdf
