Abstract

A recursive method of calculating an inverse impairments matrix is used to generate an SINR estimate, which in turn is used to generate a CQI estimate. The recursive inverse impairments matrix calculation avoids the need to perform a computationally intensive matrix inversion, allowing for faster CQI estimate generation and consuming less power.
