摘要：The move to digital modulation provides more information capacity, compatibility with digital dataservices, higher data security, better quality communications, and quicker system availability. The main objective ofthis paper is to give an overview of the digital modulation techniques used in wireless communication systems. Thispaper presents different modulation techniques with the help of MATLAB/SIMULINK that are amplitude shift keying(ASK), quadrature phase shift keying (QPSK), binary phase shift keying (BPSK), frequency shift Keying (FSK) &Onoffkeying (OOK). Simulation models of above techniques involved in signal modulation are proposed in this paperand comparative studies of the same have been done at the later stages
