Deterministic Equivalents for the Performance Analysis of Isometric Random Precoded Systems
Deterministic Equivalents for the Performance Analysis of Isometric Random Precoded Systems
We consider a general wireless channel model for different types of code-division multiple access (CDMA) and space-division multiple-access (SDMA) systems with isometric random signature/precoding matrices over frequency-selective and flat fading channels. We derive deterministic approximations of the Stieltjes transform, the mutual information and the signal-to-interference-plus-noise ratio (SINR) at the output …
