摘要

The matrix model involving the quotient of two Wishart matrices appears naturally in the investigation of multiple-input multiple-output (MIMO) multiple-access and relay channels. The available exact result for the eigenvalue density for this matrix model involves the determinant of a matrix whose dimension is related to the number of antennas in the channel. Consequently, the exact result becomes...
