Abstract
Methods and apparatus for wireless communication using a matrix of reconfigurable cells is provided. Each cell has an antenna or antenna port and is reconfigurable to operate as a transmitter, receiver, angle-of-arrival detector or power harvester. Cells can be allocated to different tasks as needed. A reference frequency signal is distributed to each cell, with an in-phase version of the signal being delivered to a first subset of cells, and a quadrature version of the signal being delivered to a second subset of cells. The first and second subsets may be interleaved for example in a checkerboard pattern. Cells cooperate in pairs for transmission or reception of quadrature amplitude modulated signals. Groups of four cells may cooperate for angle of arrival detection. The cells may be configured as interferometric transmitter/receiver cells using 90 degree hybrid couplers and power detectors.
