| 摘 要： | 介绍了在酉空时星座下的空时网格码调制的原理,在MATLBA软件环境下,对瑞利衰落信道下的网格酉空时调制的性能进行仿真,并与相同信道下未编码的酉空时码的性能进行比较.结果显示,在10-4比特误码率下相对于未编码得到8~15 dB的编码增益.

| Abstract: | The principles of the trellis-coded space-time modulation scheme that uses unitary space-time constellation were introduced. And the trellis-coded USTM system was simulated on the Rayleigh fading channel in MATLAB. The results show that 8-15 dB coding gain at BER 10^-4 can be obtained compared with uncoded unitary space-time modulation in the same channel. |
