Abstract
A multi-antenna signal encoding method comprises receiving an antenna signal and a reference signal a first mixer; producing, using the first mixer, a down-converted signal based on the antenna signal and the reference signal; receiving, at one or more second mixers, second antenna signals and second reference signals orthogonal to the first reference signal; producing one or more second down-converted signals based on the one or more second antenna signals and the one or more second reference signals; converting, using an analog-to-digital converter, a summation signal corresponding to a sum of the first down-converted signal and the one or more second down-converted signals, into a digital receive-signal; and extracting, at a processor, a plurality of digital signals from the digital receive-signal, wherein each of the plurality of digital signals corresponds to one of the first antenna signal and the one or more second antenna signals.
