VIDEO TRANSMISSION IN V-BLAST ENCODED MIMO MC-CDMA WIRELESS SYSTEM: PERFORMANCE STUDY

With the fast development in wireless communication techniques along with mobile internet and multimedia services, the demand for high data rate transmission is increased significantly. The reliable transmission of data through wireless channels offer great challenge including fading, interference and multipath propagation [1,2]. As the demand for multi-user communication such as cellular systems is increasing, it is required to have multiple access capability to transmit multiple signals simultaneously through the channel. In recent years, a new transmission technique called Multicarrier - Code Division Multiple Access (MC-CDMA) [3,4] which is the combination of Code - Division MultipleAccess (CDMA) [5] and Orthogonal Frequency Division Multiplexing (OFDM) has become most promising data transmission scheme in wireless communications. This multicarrier transmission scheme has received great attention because these combined systems possess many desirable properties for high data rate and efficient data transmission over wireless channels. The major advantage of the multicarrier technique is that it needs a lower symbol rate as compared to other transmission techniques. With a multicarrier CDMA system, for N carriers, the whol
