| 摘 要： | 从理论上给出一种Rice衰落条件下Reed-Solomon码级联空时分组码系统的差错性能分析方法,并推导给出级联码误比特率上界的数学表达式。理论分析和仿真结果表明,随着信噪比的增加,级联码系统的性能曲线迅速变好,获得了很高的编码增益。在误比特率为10-4时,与Reed-Solomon码的级联可以使衰落条件下空时分组码的性能提高大约5 dB。

| Abstract: | Based on the studies of Reed-Solomon codes and orthogonal space-time block codes over Rice fading channel,a theoretical method to estimate performance for Reed-Solomon codes concatenated orthogonal space-time block codes is presented in this paper.Upper bound of bit error rate is obtained.Simulation results show that the signal-to-noise ratio reduces about 5dB or more after orthogonal space-time block codes concatenated Reed-Solomon codes over Rice fading channel,when bit error rate is 10-4. |
