Optimal joint transmit-receive diversity (JTRD) is a multi-input multi-output (MIMO) spatial diversity technique and is designed to maximize the composite channel gain. A set of optimal JTRD weight vectors is a solution of eigen-equations or is derived by applying the singular value decomposition of MIMO channel. In this paper, instead of solving eigen-equations, a recursive solution method for obtaining the optimal JTRD weight vectors is proposed. Also proposed is the JTRD weight vectors sharing between base station (BS) and user, which makes it possible that either of BS or user carries out the recursive solution method. It is confirmed by computer simulation assuming a single-user Rayleigh faded MIMO channel that the proposed recursive solution method can obtain the JTRD weight vectors by only about 3-5 times updating and can achieve the channel capacity almost identical to the optimal JTRD.
