Abstract

This paper concerns the performance of two-way point-to-point multiple-input multiple-output (MIMO) links. In particular, the system of interest comprises a pair of multiantenna full-duplex terminals that communicate with each other through a MIMO radio channel under residual self-interference from imperfect mitigation using joint decoding for reception. The new theoretical result underlying this study is to express asymptotic achievable rates in the system whose dimensions grow without bound when detection and decoding is mismatched due to the residual self-interference and spatial data streams are separately encoded using some practical digital modulation scheme, in contrast to ideal matched decoding and Gaussian signals considered in related works. Consequently, the achievable transmission rates are illustrated based on the analytical expressions by numerical results and characterized thoroughly in symmetric scenarios where the two communicating terminals are identical. Furthermore, reference simulations show that the theoretical large-array results can be used as reasonable approximations even if the number of antennas is rather small.
