地描述成一个信号星座 Signal Constellation

  • signal constellation - 引用次数:4

    In a sense, the capacity of MIMO channel increases in accordance with antenna number in system. More over, a complex signal constellation can provide higher spectrum efficiency than a real signal constellation.

    在一定范围内, MIMO信道的容量将随系统天线数目的增加而增大;另一方面,复信号星座图映射方式将比实信号方式带来更高的系统频谱利用率。
