Title

Performance Enhancement of OFDM System in AWGN and Rician Channel by using Optimize Adaptive Coding Technique

Download Paper

Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is Basic Element in 4G mobile system. In many communication systems, OFDM is extensively useful to reduce the bandwidth and for its enhancement ability of the data rate. Performance of OFDM improved by using different channel coding through Additive white Gaussian noise (AWGN) and Rician Channel. In this paper we analyzed BER (Bit error rate) performance of 4 PSK, higher order modulators such as16-QAM,64-QAM System over AWGN and Rician Channel by using convolutional coding. In OFDM system, at receiver the Signal to noise ratio is estimated and then transmitted to the transmitter through feedback channel, the transmitter according to the estimated SNR select appropriate modulation scheme and coding rate which maintain constant bit error rate lower than the requested BER. Simulation is carried out on the software named MATLAB
