Abstract
A communications device includes an antenna array comprising antenna elements for receiving at least N spatially independent signals, and a receiver coupled to the antenna array. The receiver includes an analog receiver circuit for receiving the N spatially independent signals, and has a bandwidth of at least N times an information bandwidth of the spatially independent signals. The receiver further includes a digital receiver circuit coupled to the analog receiver circuit, and samples the N spatially independent signals at a rate of at least N times a Nyquist rate which would have been required if a single antenna element had been used to receive signals. A processor is coupled to the digital receiver circuit for demultiplexing the sampled N spatially independent signals.
