Joint source channel coding with MC-CDMA in capacity approach

In conventional system of wireless communication the source and the channel coding are used in different modules that increases the system complexity, cost and overall processing period. To make it more efficient, both the source and channel coding modules are combined in a single processing block, which not only decreases the system complexity but also reduces the overall processing cost. Multi Carrier Code Division Multiple Access (MC-CDMA) technique which is a combination of CDMA and Orthogonal Frequency Division Multiplexing (OFDM) provides higher capacity. The proposed approach combines joint source channel coding with MC-CDMA. Through integrity check and receiver control mechanism, our system is able to subscribe to a desired broadcast session. The proposed approach result in a capacity which is nearly equals to the upper bound of the ratio C/H where C is the channel capacity and H is the entropy of the source.
