Performance Enhancement of MIMO MC-CDMA System employing Cylically Rotated Complete Complementary Codes

Abstract

Wireless communication needs very high data rate and throughput in order to meet increasing demand for multimedia applications. MC-CDMA technique along with multiple input multiple output (MIMO) technique is used to increase data rate and to reduce the channel impairments. Spreading code plays a major role in CDMA technique, Cyclically rotated complete complementary codes (CRCCCs) are used for spreading which have perfect auto-correlation and cross correlation properties. Bit error rate (BER) can be reduced and have other advantages like high data rate, high throughput, reduced inter symbol interference (ISI) and multiple access interference (MAI). MIMO MC-CDMA system employing CRCCCs is designed and simulation results are shown.
