| 摘 要： | 针对准静态受遮蔽的 Rician 衰落信道,在收端已知信道状态信息的条件下,文中分析了空时格码的性能.推导了码字差相关阵为对角阵的空时格码系统的成对差错概率的确切表达式,得到了相应空时格码在准静态受遮蔽的 Rician 衰落信道中的性能上界。仿真结果表明,在遮蔽不太严重的信道中,文中得到的 union 界与相应编码系统的实际性能有很好的近似度。

| Abstract: | With the perfect channel state information,the performance of space-time trellis codes over quasi-static shadowed Rician fading channels was analyzed.For space-time trellis code with the codeword difference correlation matrix being diagonal matrix,an exact expression of the pairwise error probability over shadowed Rician fading channels was derived and some upper bounds on the frame and bit error probability of this system obtained.By comparing it with the simulation results,it is showed that the proposed u... |
