Performance Estimating for Space-Time Block Coded Cooperative Communication System
A new cooperative communication system based on space-time block coding (WCC-STBC) is proposed in this paper, and a closed-form expression of bit error rate for this WCC-STBC system is also deduced. The results through theoretical analysis and computer simulation show that the diversity gain, which is dependent on the characteristics of the users individual channel and the inter-user channel between them, could be obtained in the WCC-STBC system. When BER is 10-3, and if the inter-user channel is 5dB better than their individuals, about 3dB gain could be gotten in WCC-STBC system; and if one users channel is 5dB better than his partners, 5dB gain for the performance of the worse user could be improved while that of the better one is less loss, only about 0.5dB or so.
