BER of OFDM system using concatenated forward error correcting codes (FEC) over Nakagami–m fading channel
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 9
Abstract
In this paper, we present an efficient technique for the BER of audio signal in OFDM system, using concatenated forward error correcting (FEC) code namely convolution code and reed Solomon code, over Nakagami–m fading channels In FEC concatenated channel coding, the OFDM system uses Reed Solomon (RS) encoder of (255,239,8), with Convolution encoder of ⅔ and ¾ -rated codes under QPSK digital modulation. The simulation study is made with the development of a computer program written in MATLAB source code on the processing of recorded audio signal under additive Nakagami–m fading channels. The simulation results of estimated Bit error rate (BER) show that the implementation of concatenated RS(255,239,8) code with Convolutional code under QPSK modulation technique gives better results in terms of Bit error rate (BER) as compared to only Convolutional code under QPSK modulation.
