Array Beamforming Synthesis for Point-to-Point MIMO Communication

While transmit and receive beamforming for the multiple-input multiple-output (MIMO) point-to-point channel is a well-studied topic, existing algorithms cannot specify effective beamformers for certain situations. To address this deficiency, we present an iterative algorithm that can establish beamformers based on different channel information available to the transmitter and receiver, different receiver architectures, and different constraints on the power radiated by the transmit array. Simulation results based on modeled and measured channels demonstrate that the algorithm effectively accommodates a wide range of conditions and that the performance achieved with the approach matches that obtained using existing algorithms that are applicable only to specific conditions.
