Abstract

Novel cascaded coding method is proposed to overcome inter symbol interference (ISI), composed of frequency selective Rayleigh fading channels in this paper. The proposed method consists of combined Turbo Coding (TC), Permutation Coding (PC) and M-FSK modulation. Computer simulations are performed to verify the efficiency of the proposed method (TPC) and compare with Reed-Solomon and Convolutional Coding (RS-CC) and Turbo coding (TC) in frequency selective Rayleigh fading channels. In fact, PC helps to remove the error floor of an equalizer and M-FSK helps to recover data in highly noisy environment, and finally TC is successful reducing error rate. Therefore, the proposed technique provides high SNR improvement of approximately 6 dB in AWGN and 5 dB in frequency selective channels.
