Abstract:

In this paper, the performance of a convolutional encoded orthogonal frequency-division multiplexing (OFDM) based wireless communication system has been simulated in terms of bit error rate (BER). In FEC channel coding, the OFDM based wireless communication system incorporates a convolutional encoder under various digital modulation schemes (QAM, QPSK, 8QAM, 8PSK, 16QAM, 16PSK, 32QAM and 32PSK). The computer simulation results on BER over an Additive White Gaussian Noise (AWGN) and other fading (Rayleigh and Rician) channels demonstrate that the convolutional encoded OFDM system outperforms with QAM modulation technique as compared to other digital modulation schemes and the system is highly effective to combat inherent interferences under Rayleigh and Rician fading channels. It has been anticipated from the simulation study with synthetically generated data that the performance of the communication system degrades with the increasing of noise power.
