Max–Min Weighted Achievable Rate for Full-Duplex MIMO Systems

In this letter, we aim to maximize the minimum weighted achievable rate of the two links in multiple-input multiple-output full-duplex systems via precoder design. With bidirectional communication and unidirectional communication fashion considered, our system model involves limited dynamic range effect and channel estimation error. We propose D.C. (difference of two convex functions) based algorithms to solve the highly non-convex optimization problem, and the complexity, convergence and optimality of proposed algorithms are discussed.
