Signal-to-noise estimation in wireless communication devices with receive diversity

摘要

This disclosure is directed to techniques for estimating signal-to-noise ratio (SNR) of signals received by a wireless communication device. The techniques take advantage of spatial receive diversity in a wireless communication device to achieve accurate estimates of SNR. In general, a spatial projection wiener filter function can be applied to incoming symbol estimates to support efficient computation of SNR. The estimated SNR can be used to produce power control commands for use in forward power control.
