Concatenation and Implementation of Reed- Solomon and Convolutional Codes

Abstract

High bit error rates of the wireless communication system require forward error correction (FEC) methods to implement on the data to be transmitted. In this paper, the performance of convolutional, block and concatenated coding schemes are used to encode the data stream and are evaluated. Simulation is performed to find the Bit Error Rate(BER) of the Convolutional(CC) and Reed-Solomon(RS) codes and the best outcome is used to model the RS-CC and CC-RS concatenated codes. By concatenating these two codes, an improved BER performance is obtained due to benefits of RS codes correcting burst errors and convolutional codes correcting random errors that are caused due to a noisy channel. Finally, a comparison between both the coding techniques and also with the uncoded data transmission technique is done.
