Abstract
Recently, a cooperative communication technique called coded cooperation is presented. The cooperation in this method is performed by way of channel coding as a substitute for a direct relay or repetition. In a multi-user environment, more than one single antenna mobiles cooperate in virtual MIMO system to accomplish transmit diversity while supporting the same information rate and transmission power. Concatenated Reed Solomon and convolutional codes, RSCC, are effective channel codes to reduce the noise. So they have been employed by some wireless communication standards such as IEEE 802.16e WiMAX. In this paper, we compare the performance of RSCC, concatenated codes, coded cooperation to RS, codes without concatenation, coded cooperation in terms of bit error rate with various SNR and Doppler shift values utilizing higher order modulation techniques. We adopt the structure of physical layer specifications of IEEE 802.16e WiMAX. The results illustrate the performance of RSCC coded cooperation as compared to RS coded cooperation is significantly supreme at medium and high SNR ranges and at low and medium Doppler shift ranges. The results show RSCC coded cooperation is robust for a high transmission rate operation as well.Keywords
