Abstract :
Due to the disability of MSINR beamforming receiver to correct for the carrier frequency offset in MC-CDMA uplink systems, we present a new combined MSINR beamforming and MMA algorithm. While MSINR beamforming provides an appropriate beam pattern having its maximum gain along the desired user direction, the suggested MSINR-GCMMARY can capture the desired signal and compensates for carrier frequency offsets. The enhanced performance of the proposed receiver is proved by the simulation results.
