Zusammenfassung:A rake receiver for processing a multi-path input signal received from a communications channel, wherein each multi-path component of the multi-path input signal comprises one or more symbols, comprises a plurality of fingers and a demodulator. Each of the plurality of fingers is adapted to receive the multi-path input signal and provide a sequence of input samples corresponding to a multi-path component of the multi-path input signal. The demodulator is adapted (i) during a single clock period, to receive and process one or more input samples corresponding to only one of the fingers, (ii) for each of the fingers, to accumulate multiple processed input samples to form a symbol, and (iii) to provide the formed symbols for all fingers.
