Abstract
Apparatuses, methods, and systems for analog spatial multiplexing are disclosed. One apparatus includes a receiver, wherein the receiver includes a plurality of antennas operative to receive a plurality of wireless signals, a plurality of tunable time delays, and a plurality of frequency response equalizers, wherein a time delay of each of the tunable time delays is adjusted based on a feedback of measurements of one or more pilot tones of more than one output of the plurality of frequency response equalizers. The receiver further includes a plurality of frequency up-converters generating a plurality of frequency up-converted signals, a MIMO processor receiving the plurality of frequency up-converted signals, wherein the MIMO processor adjusts a gain and phase of the of the frequency up-converted signals based on the measurements of the pilot tones, and a plurality of frequency down-converters receiving and frequency down-converting output signals from the MIMO processor.
