1. An apparatus for processing signals received on a multiple antenna receiver system (MARS), comprising: a switch for selecting one of a plurality of signal paths associated with a respective plurality of antennas, wherein, in operation, the switch is operable to select signal paths such that, over time, signals received from the plurality of antennas are multiplexed to form a single analog signal; a sampled digital signal processing (DSP) block, coupled to the switch, for processing signals of the signal paths to remove inter-antenna symbol interference (IASI) and inter-symbol interference (ISI).
