| 摘 要： | 针对信道相关严重影响空间复用系统性能和容量的问题,研究发射天线数与容量和符号向量错误概率(VSER)的关系。并通过仿真实验从容量和VSER两方面研究天线选择的必要性。结果表明:在发射和接收天线数均为4,发射天线间距为2倍波长,发射角度扩展为2°时,合理的天线选择不但可以降低系统成本,还可以提高系统容量。

| Abstract: | Correlated fading affects the performance and capacity of spatial multiplexing systems seriously. The effects of the number of transmit antenna on the capacity and VSER were studied. The necessity of antenna selection was demonstrated from both the capacity and VSER aspects. Simulation results illustrate that appropriate antenna selection can not only reduce the cost of system, but also improve the capacity when both the number of transmit antenna and receiver antenna are 4, transmit antenna spacing is 2-wavelength and scattering angle is 2 degree. |
