Abstract :
We present a multiple-input-multiple-output (MIMO) code-division-multiple-access (CDMA) communication system based on complete complementary (CC) codes (CC-CDMA) in a time-dispersive (i.e. frequency-selective fading) channel. This system utilizes a novel combination, which consists of orthogonal CC codes for data spreading and a suitably designed multiuser-detector (MUD) algorithm, in order to enhance the current 3rd generation (3G) mobile systems. The simulation results for the CC-CDMA system, obtained in a frequency-selective fading channel, reveal significant improvement in bit-error-rate (BER) performance, and consequently the achieved high data rates (HDR) compared with a conventional Walsh codes based MIMO CDMA (Walsh-CDMA) system.
