Research of Coded Cooperation Scheme Based on Multidimensional Product Codes

Multidimensional product codes are a kind of mature EEC(errorcorrecting codes) with good performance and  agile code structure。A new style coded cooperation scheme based on multidimensional product codes is discussed particularly in this paper, which uses the different dimension parity bits to cooperate. This coded cooperation scheme can get large diversity gain. Multidimensional product codes with extended hamming codes are used in theory analysis and computer simulation, slow fading channel and fast fading channel are two kinds channel model.  The result of simulation shows that: on slow fading channel, Bit Error Rate (BER) is 10-3, cooperation level is 50%, when the interuser SNR is larger than 10dB，large gain(>8dB) is obtained; on fast fading channel , coded cooperation  make the user with worse uplink channel perform better. The coded cooperation will have better application, in view of its practicability and good performance.
