Abstract

Today, communication system requires high capacity and faster data transmission with minimum error and losses. Wireless communication using multiple input multiple output (MIMO) systems enables increased spectral efficiency for a given total transmit power and high reliability. This project is to analyze the performance of MIMO-CDMA with comparison to conventional of Code Division Multiple Access (CDMA) system. The performance is often measured as the average bit rate (bit/s) the wireless link can provide or as the average bit error rate (BER). In this project, simulation are done to design the simulation model which is conventional CDMA, MIMO-CDMA with two-transmit tworeceive (2Tx2Rx) and MIMO-CDMA with four-transmit four-receive (4Tx4Rx). Then, the comparison between conventional CDMA system and MIMO-CDMA system is made to investigate the system performance. All simulation models are done using the MA TLAB software. The result shows that MIMO-CDMA technique gives better performance than conventional CDMA system in term of bit error rate (BER) and also capacity performance. From this analysis also, the performance can improve better when the number of antenna is increase.
