A method of signal processing, or corresponding apparatus, includes providing multiple analog receive signals at respective antennas and selecting one antenna at a time in an iterative manner, to cycle through the antennas and provide a multiplexed analog signal. The multiplexed analog signal is filtered at a filter to pass a predetermined frequency band. The multiplexed analog signal is sampled at a single analog to digital converter to generate a multiplexed digital signal. The multiplexed digital signal is demultiplexed to generate multiple digital signals for digital processing. Sharing a receiver and ADC among multiple antennas results in reduced cost and power. Such cost and power reductions in turn enable larger antenna arrays than are available with prior art techniques, thereby promoting increased throughput and coverage.
