Abstract :
In this paper, we propose a simple adaptive antenna array based MC-CDMA receiver that combines efficient blind adaptive beamforming based on maximum signal-to-interference-and-noise ratio (MSINR) criterion with the Multimodulus Algorithm (MMA) for a MC-CDMA uplink system. The beamformer is used to enhance the desired signal and reduce the co-channel interference from other directions and compensates the carrier frequency offset. The MSINR beamforming is used to guide the initial weights of the multimodulus array in order to select the desired signal, resulting in MSINR-GMMARY. Computer simulations show the high efficiency of the proposed MSINR-GMMARY in separating cochannel signals even in the presence of channel fading and multipath propagation and carrier frequency offset.
