Abstract

Apparatus and method for processing a received pilot to obtain noise estimation of a pilot channel and processing a received first signal channel, separately from a second signal channel that is orthogonal to the first signal channel, to obtain a signal level of the first signal channel. The noise estimation and the signal level are used to calculate a SNR value. Detection on the first channel is done by checking the SNR and the sign of a soft metric.
