摘要：A wireless transmit/receive unit (WTRU) is configure to receive and samplewireless signals in a shared spectrum where the wireless signal comprise encoded
symbols. The WTRU has a channel estimation device configured to process receivedsignal samples to produce an estimate of a channel response of the received signalscorresponding to a matrix H. The channel estimation device is preferably configured toprocess the received signal samples to produce an estimate of noise variance of thereceived signals. The WTRU preferably has a two stage data estimator that includes achannel equalizer and a despreader. The channel equalizer is configured to processreceived signal samples using the estimated channel response matrix H and the estimateof noise variance to produce a spread signal estimate of the received signals. Thedespreader is configured to process the spread signal estimate of the received signalsproduced by said channel equalizer to recover encoded symbols of the received signals.
