| 摘 要： | 重点研究了基于相干检测条件下的比特交织编码(B it-Interleaved Coded M odu la-tion-B ICM)系统,针对16-QAM、8-PSK和QPSK调制方式,仿真比较了高斯信道和频率非选择性瑞利信道下的截止速率。发现在发送端与接收端已知和未知信道特性时,相应的截止速率也不同。这可以为系统设计提供性能参考。

| Abstract: | This paper analyzes the cutoff rate of a bitinterleave coded-modulation and coherent detected system,based on different modulation schemes and over both Gaussian and frequency nonselective Rayleigh fading channels.Simulation results demonstrate that this rate is different depending on whether the channel state information is available or not for transmitter and receiver.The results can be a reference for further system design. |
