Methods Circuits Systems and Associated Computer Executable Code for Performing Beamforming Based Wireless Communication

摘要

Disclosed are Bridging circuitries (BC100), and access points comprising BC100, which may be adapted to perform signal interfacing, signal conditioning, signal analysis and/or other signal processing to signals passing between RF Chains and Baseband Modem Circuits (BBMC), wherein interfacing, conditioning, analysis and/or processing may include: (1) Tx beam forming, (2) Rx Beam forming, (3) per beam Rx packet detection, (4) signal analysis and characterization and (4) MIMO spatial expansion. BC100 may include signal processing circuitry adapted to perform simultaneous multi-DOA estimation and packet detection upon multiple beams. BC100 may also be adapted to coordinate operation of the RF Chains and BBMC relative to one another. BC100 may also comprise memory for storing signal characteristics which may be utilized to improve its operation
