Abstract:
1. An apparatus for processing signals received on a multiple antenna receiver system (MARS), comprising: a plurality of antennas; a switch coupled to the plurality of antennas for switchable coupling to each selected one of the plurality of antennas in sequence, to form a single analog signal with discrete sequential samples from each of the antennae; an analog-to-digital converter (ADC) coupled to the switch; a switch synchronization and control block coupled to both the switch and to the ADC to synchronize the operation of the switch and the ADC such that the ADC converts the single analog signal from the switch to sampled digital signals from each antennae; and a digital signal processing (DSP) block, coupled to the ADC, for processing the sampled digital signals from each antenna to remove inter-antenna symbol interference (IASI) and inter-symbol interference (ISI), and wherein the DSP block includes:
