Abstract: A receiver includes an input for receiving an input signal comprising a plurality of symbols from a plurality of multi-path transmission channels, and a plurality of fingers are connected to the input. Each finger includes a plurality of demodulation units assigned to the plurality of multi-path transmission channels for demodulation thereof, and each demodulation unit includes a channel correction circuit. A shared memory is upstream from the channel correction circuits and is shared by the demodulation units for performing a delay function therefore. A controller successively time-division multiplexes read and write access operations to the shared memory during successive time slots so that one symbol, for each active multi-path transmission channel, can be read and written during each time slot.
