  • A communication system With Cooperative Communication based on Space-Time Block Coding (WCC-STBC) is proposed in this paper. A closed-form expression of bit error ratio for WCC-STBC system is also derived. The results through computer Monte Carlo simulation show that the diversity gain, which is dependent on the characteristics of the users individual channel and the cooperative channel between them, can be gotten in the WCC-STBC system. When BER is 10-3, and if the cooperative channel between them 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.
