Performance analysis of massive multiuser multiple-input multiple-output systems with block diagonalisation

ABSTRACT:

In this study, the authors gift asymptotic capability analysis of block diagonalisation (BD)-precoding and BD with house-time block code schemes for future wireless communication systems. Assuming that the amount of base station antennas N and the amount of antennas per user M are massive whereas their ratio remains bounded, the capability expressions for these two schemes are derived in each cases of good channel state info (CSI) and imperfect CSI, respectively. Based on this, the authors obtain the optimal number of user terminals K to be served by the system. Closed-form expressions of the optimum coaching length based mostly on the essential system parameters are derived for practical implementation. The accuracy of the analysis is validated by numerical results with totally different parameter settings. It has been shown that the capability expressions are correct even for tiny M.
