In this paper, we consider the combination of antenna array and multi-carrier code division multiple access (MC-CDMA) in the presence of carrier and synchronization offsets. MC-CDMA systems are regarded as suitable modulation techniques for third and fourth generation cellular systems to handle unprecedented demands for wireless communication. On the other hand antenna arrays have been shown to improve the coverage quality and system capacity by suppressing co-channel interference. In this paper, the proposed scheme will be evaluated using two different pulse shaping filters. While one of the pulse shaping filters allows the low complexity receiver implementation, the other requires costly match filtering. We investigate the performance of two cases via computer simulations.
