This paper investigates the problem of hybrid
transceiver design for dual-functional radar-communication
(DFRC) system. Specifically, we introduce an information embedding
scheme for the DFRC system with a subarray structure.
The hybrid transmit/receive beamformers are designed by
maximizing sum-rate under constraints of power and similarity
between the designed bemaformer and the reference one
with good beampattern property. Since the formulated problem
is difficult to tackle, we propose an alternating optimization
method based on the alternating direction method of multipliers
(ADMM) framework to obtain the hybrid beamformer.Numerical
simulations are provided to demonstrate the effectiveness of the
proposed schemes.
