| 摘 要： | MIMO通过多天线发射多数据流并由多天线接收实现最佳处理，可实现很高的容量和频谱利用率，这种最佳处理是通过空时码实现的。本文依照一个实际信道模型，假定Rayleigh或Rice准静态平坦非相关和部分相关信道，分析了STBC的信道容量，并进行Monte-Carlo模拟仿真。结果表明STBC的容量远低于其理论限，特别是对于大的N和M。

| Abstract: | The Multiple-Input Multiple-Output (MIMO) technique performs optimal processing by multiple transmitting and multiple receiving data stream, which can improve capacity and spectral efficiency. The processing is obtained by space-time codes. This paper analyses channel capacity of space-time block codes(STBC) and gives monte-carlo simulations with the assumption that channel is Rayleigh or Rice, quasi-static and flat, uncorrelated and partially correlated according to a realistic channel model. The results show that the capacities of STBC are significantly lower than those associated to theoretical limits, specially for large N and M. |
