A receiver for acquiring a signal through a propagation channel, the receiver comprising channel estimating means () for producing stream of CIR estimates for the channel, a plurality of doppler filtering means () for filtering the CIR stream in parallel and selecting means () for selecting the output of one of the doppler filtering means for use in recovering said signal.

Refinement of channel estimation with a bank of filters

A method of producing soft decisions for a signal, wherein a model provides an expression for an LLR for the signal, the LLR expression is dependent on noise power in the signal and can be rendered in a form independent of the noise power, wherein the method comprises evaluating the noise power independent expression using values from the signal to produce soft decisions, calculating a weight expressing the noise power affecting a soft decision relative to the noise power affecting at least one other soft decision and applying the weight to its respective soft decision.
