Abstract:
1. A receiver for acquiring a signal through a propagation channel, the receiver comprising: channel estimating means for producing a stream of channel impulse response (CIR) estimates for the channel; a plurality of filtering means for filtering the CIR stream in parallel, each of the plurality of filtering means filtering the stream of CIR estimates for the channel; selecting means for selecting an output of one of the plurality of filtering means for use in recovering said signal; and delay means for applying a delay, the same as a timing change when a receiver timing of the signal is modified, to the selected filtering means output, wherein said delay is adjustable in order to at least attempt to synchronize a timing relationship between the receiver timing of said signal and the output timing of the selected filtering means output irrespective of which of the plurality of filtering means has been selected to provide the selected filtering means output.
