摘要

In this study, the authors investigate the energy-efficient resource allocation in a multiuser downlink multiple-input multiple-output (MIMO) orthogonal frequency-division multiple access system with block diagonalisation. Unlike the existing works in which one subcarrier is exclusively used, they consider the multiple user MIMO case on each subcarrier. An optimisation problem involving user selec...
