sir i have to prepare a model and project on the comparison between BPSK and QPSK. can you please help me in making the model..or you can provide any information regarding this topic.

@lavanya: Am hoping that you will be able to develop the 8QAM symbol error rate code using the 16QAM case as reference.

@Shareef: Is it modulation and demodulation mapping i.e. bits to constellation?
