This paper poses full-duplex phase shift keyed communication between two digital phased arrays as an estimation problem and outlines an approach to minimizing the symbol phase estimation error. We develop an information-theoretic bound on the estimation error and a related feasible optimization objective function for the communications link in terms of the transmit and receive beamformers. We also apply a genetic algorithm to search for a transmit/receive aperture partitioning that minimizes the estimation error bound.
