  • A novel two-user cooperative diversity scheme based on concatenated channel code and distributed space-time block code is proposed in this paper, and the close form expression and numerical results of channel capacity, outage probability and bit error rate for the quasi-static rayleigh fading channels are also presented by theoretical derivation and system simulation. Through integrating with channel coding and space-time coding, system capacity has been greatly enlarged, and the outage probability is distinctly reduced also. The performance analysis and simulation for the transmitted scheme, which is based on concatenated convolution code and distributed space-time block code under the interuser channel is noisy, is carried out exhaustively. Numerical results show that, even though the interuser channel is noisy, the proposed scheme in this paper is better than traditional cooperative diversity in every respect, such as the channel capacity raised obviously, outage probability and bit error rate decreased greatly.
