Antenna gain mismatch between transmitter and receiver circuits has been regarded as an obstacle for exploiting channel reciprocity between uplink and downlink channels in time-division duplex (TDD) multiple-input multiple-output (MIMO) systems. To the best knowledge of the authors, little work to date has been on about the impact of antenna mismatches on the precoding vector. Motivated by this fact,...
In this paper, power allocation scheme for clusters by mobile station (MS) is investigated in the uplink of a multi-user multiple-input multiple-output (MU-MIMO) and orthogonal frequency division multiplexing access (OFDMA) cellular system. In system level simulation works, without the knowledge of how many clusters will be assigned to a MS, it is a puzzle to decide how much transmission power should...
