A simplified approach for joint source and channel coding for data transmission over wireless channel

Abstract

A simple and efficient method for communication of text information using joint source-channel coding is presented in this paper. The information is encoded by the use of symmetric reversible variable length code and corresponding header sequence is generated. The header information, headers and codewords forms a frame. Since the header plays a crucial role for decoding the codewords at the receiver, it is channel encoded and the coded frame is transmitted after modulation. Orthogonal Frequency Division Multiplexing (OFDM) technique, which is known to provide high data rate and better performance over wireless channels, is used in designing the transceiver system.
