摘要

给出了存在多径信号传播时具有大量接收天线的移动通信信道的固定信道信息容量表达式。结果表明，该信道的容量接近无干扰的正交高斯信道的信息容量。提出了采用自适应线性MMSE接收机和自适应干扰抵消的系统，作为实现理论容量的低计算复杂度解决方案。

Information capacity of a multipath mobile communication channel with large number of receiving antennas

The expression for stationary channel information capacity of a mobile communication channel with a large number of receiving antennas in the presence of multipath signal propagation is shown. It has been shown that the capacity is approaching information capacity of the orthogonal Gaussian channel with no interference. The system with adaptive linear MMSE receivers and adaptive interference cancellation is presented as a possible low computational complexity solution achieving the theoretical capacity.
