中文说明：
此函数计算了遍历性和中断的MIMO瑞利信道，考虑到没有CSIT（平均功率分配）和完善CSIT（注水功率分配）信道容量。在这两种情况下假设是理想的。该频道跟据克罗内克模型假设空间相关，但在时间上不相关。
English Description：
This function calculates the ergodic and interrupted MIMO Rayleigh channel, considering the channel capacity without CSIT (average power allocation) and perfect CSIT (water injection power allocation). In both cases, the hypothesis is ideal. The channel is assumed to be spatially related according to the croneck model, but not spatially related.
