Abstract

Orthogonal Frequency Division Multiplexing (OFDM) has gained increased interest due to its robustness against multi-path interference and high spectrum efficiency. OFDM is a suitable candidate for high data rate transmission with forward error correction (FEC) methods over wireless channels. In this paper, the system throughput of a working OFDM system has been enhanced by channel coding technique like Reed Solomon code& Turbo Code. Forward Error Correcting codes are a new class of codes that can achieve exceptional error performance and energy efficiency at low signal-to-noise ratio. The simulation is made with the development of Models in the SIMULINK & computer program written in MATLAB source code on the random data under additive white Gaussian noise (AWGN) channel. The simulation results of estimated Bit error rate (BER) show that the implementation of RS code with ½ -rated under QPSK modulation technique is highly effective to combat inherent interference in the communication system.For decoding of Turbo code, MAP decoding algorithm is used. In case of Turbo code BER performance is substantially improved by increasing number of iterations used in the decoding process
