Abstract

This paper presents a MIMO adaptive beamforming in the MC-CDMA system. At the transmitter, a space-time block coding is concatenated to MC-CDMA modulation. At the receiver, an adaptive GSC beamformer is to filter the desired user and suppress interferences by beamspace processing. Combined with the space-time block coding, the smart antenna forms multi-mainbeams toward the desired user. The system performance is evaluated by illustrating the estimated DOAs, beampatterns, weight convergence and BERs in both the flat and frequency selective fadings.
