Performance Evaluation of a Cooperative OFDM System with implementation of DAF and AAF Relaying Protocols on Color image transmission

Abstract

In this paper, we investigate the performance of a single-relay cooperative wireless communication system with implementation of Orthogonal Frequency division multiplexing technique under Amplifyand-Forward (AAF) and Decode-and-Forward (DAF) relaying protocols on color image transmission. The system under investigation incorporates four conventional signal combining schemes such as Equal Ratio Combining (ERC) and Fixed Ratio Combining (FRC), Signal to Noise Ratio Combining (SNRC) and Enhanced Signal to Noise Ratio Combining (ESNRC) under BPSK and QPSK digital modulations. In the present study, results of BER simulation in AWGN and Raleigh fading channels shows that the system outperforms in ERC combining scheme as compared to others (FRC, SNRC and ESNRC) under BPSK digital modulation and AAF relaying protocol. It is observed that a quite

“…M. M. Hossain et al made a comprehensive study elucidating the performance of a single relay cooperative OFDM system under AF and DF relaying strategies on Color image transmission. The results of BER simulation in AWGN and Raleigh fading channels show that the AF relaying protocol supported cooperative OFDM system outperforms in ERC signal combining scheme as compared to others (FRC, SNRC and ESNRC) under BPSK digital modulation [9]. J. J. Sadique et al presented for a convolutionally encoded MIMO SC-FDMA wireless communication system on encrypted color image transmission and the implementation of QAM digital modulation technique with ZF channel equalization provides satisfactory result for convolutionally encoded MIMO SC-FDMA wireless communication system [10].…”

“…Besides, [15] has shown that BER was considerably improved by using multiple relays with low SNR value for audio and text data. Based on current wireless standards, such as IEEE 802.16j, in [8][9][10][11][12][13][14][15][16] an OFDM based multi-hop relaying system has been proposed. The issues with implementation of cellular network based on OFDM-based multi-hop was accounted by Can et al [17].…”
