Abstract

The power of a signal received on a spatial channel in a wireless radio communications system can be estimated. One embodiment of the invention includes receiving a signal at a plurality of antenna elements, the received signal including a first component from a first radio and a second component from a second radio. Then the contribution of the first component to the received signal may be estimated by calculating a first power estimate for the first radio using the received signal, calculating a second power estimate for the second radio using the received signal, and estimating the contribution of the first component to the received signal, the estimation using the first power estimate and the second power estimate. In one embodiment the first power estimate is an SINR of the first component.
