Performance of BCH and RS Codes in MIMO System Using MPFEC Diversity Technique

Abstract

Multipath propagation phenomenon often causes Inter-Symbol Interference (ISI) because several copies from the originally transmitted signal travel in different directions and reach the destination with different time delays. This paper offers a new diversity technique to eliminate the effect and utilise multipath propagation phenomenon. The new diversity technique is known as MultiPath Forward Error Correction (MPFEC) technique. The MPFEC technique considers some of the multipath copies as an existing resource (redundant copies of the transmitted signal) which can be utilised to enhance the performance of Forward Error Correction coding (FEC) techniques, hence saving significant channel resources otherwise given to a feedback channel, without adding redundancy. Two different coding techniques BCH and RS coding are used in the simulation to perform the Bit Error Rate (BER) analysis. The result reveals that BCH and RS codes performance can be enhanced by utilising the MPFEC technique without increasing the number of redundancy. This paper is implemented by using MATLAB. The results are analysed and compared.
