On MIMO channel capacity, correlations, and keyholes: analysis of degenerate channels

S. Loyka, A. Kouki
2002 IEEE Transactions on Communications  
It has recently been demonstrated that zero correlation of a random multiple-input multiple-output channel is not a guarantee of its high capacity. Degenerate channels exist, which have zero correlation and still low capacity. In this letter, we provide a statistical analysis of this phenomenon, formulate the general condition for a channel to be degenerate, and propose a method to estimate its capacity. Index Terms-Channel capacity, correlation, keyhole, multipleinput multiple-output (MIMO).
