Abstract :
A less complex system by integrating non-coherent differential amplitude and phase shift keying modulation with multi-carrier code division multiple access (DAPSK-MC-CDMA) is introduced. The proposed DAPSK-MC-CDMA system can reduce the system complexity and also maintain a good performance as well as high spectral efficiency. Simulation results illustrate that the induced power of multiple access interference (MAI) in the DAPSK-MC-CDMA is much less than the conventional MC-CDMA system
