Abstract
Systems and methods are disclosed for transmitting signals between a transmitter and a receiver by differentially estimating channel coefficients for each of the antenna elements relative to a reference antenna element; determining beam weights to remove oscillator induced phase or offset; and applying a correction (beamforming solution) at the transmitter to make the phase of the received signal from different antenna elements to be coherently combined at the receiver.
