Patent ID: 8798103

Claim:
A multi-antenna device comprising: a plurality of antennas; a plurality of receivers, each linked to one of the antennas in a one-to-one manner; a multiplexer configured to generate a composite analog signal from a plurality of different analog radio frequency (RF) signals, one received from different ones of the plurality of antennas, wherein said multiplexer comprises: a plurality of local oscillators, one communicatively linked to each receiver, wherein each of the local oscillators generates an output analog signal, wherein the local oscillators, the receivers, and the antennas receive or process analog signals in parallel with and independent of each other; and a mixer for combining the output analog signals of the local oscillators to generate the composite analog signal; a baseband filter for filtering the composite analog signal; an analog to digital converter for converting the previously filtered composite analog signal after being filtered by the baseband filter into a composite digital signal; and a de-multiplexer configured to generate a plurality of different digital signals from the composite digital signal produced by the analog to digital converter, wherein each of the different digital signals corresponds to one of the different analog RF signals in a one-to-one manner.
