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。

-This function calculates the ergodic and outage capacity of a MIMO Rayleigh

channel considering no CSIT (equal power allocation) and perfect CSIT

(waterfilling power allocation). In both cases perfect CSIR is assumed. The

channel is assumed to be spatially correlated according to a Kronecker

model but temporally uncorrelated.
