Abstract
The present system and method provides a spatial multiplexing scenario that is performed purely in the analog domain when transmit and receive arrays are in Line of Sight (LoS) and hence significantly reduce the DSP requirements of massive MIMO systems.
Claims13
A method for analog, line of sight (LoS) spatial multiplexing communication for recovering one or more of analog transmit signals from two or more of analog receive signals, comprising:
- processing the two or more analog receive signals by applying at least a portion of an inverse steering matrix to the two or more analog receive signals;
- and
- extracting the one or more analog transmit signals from the inverse steering matrix processed two or more analog receive signals;
- wherein the inverse steering matrix is based at least in part on a fixed array-to-array distance.
