qpsk transmitter a receiver, in design to simulink with AWGN,noise.

OnPerformanceLimitsofDFTSpreadOFDMSystems DFT Spread OFDM has been proposed recently to reduce the Peak to Average Power Ratio (PAPR) of conventional OFDM transmission. Besides PAPR reduction, an important implication of DFT Spreading is that the ind
