| Abstract | ||||
| This paper investigates the performance of a coded cooperative relay based Orthogonal Frequency Division Multiplexing (OFDM) wireless communication system using native rate 1/2 convolutional code and rate 1/3 turbo code. These investigations are focused on evaluating the performance of the proposed coded cooperative wireless communication system over both Additive white Gaussian Noise (AWGN) channel and different Stanford University Interim (SUI) channel models. The performance of the proposed coded cooperative relay based system is evaluated using MATLAB computer simulations and compared with direct transmission and other cooperative protocols i.e., Amplify-and-Forward (AAF) and Decode-andForward (DAF). The performance indicators used for comparison are Bit-Error Rate (BER) and spectral efficiency. The results show that the proposed coded cooperative system achieves lower Signal-to-Noise Ratio (SNR) values for the desired BER and achieves high spectral efficiency as compared to direct transmission, AAF and DAF based cooperative protocols. Finally, the results of computer simulations are included to demonstrate the efficiency of the proposed scheme. | ||||
