The multi-user multiple input multiple output (MU-MIMO) downlink (DL) transmission solutions based on the frequency division duplex (FDD) mode, which is widely investigated in 3GPP Long Term Evolution-Advanced (LTE-A), has been found to fail in improving the throughput with the distributed antennas in previous work. After clarifying the reason for the throughput deterioration by taking insight into...
The multiple input multiple output (MIMO) technology and the distributed antenna system (DAS) have emerged as the promising candidates for the future mobile communications. In this paper, we observe the downlink (DL) transmission in a single-cell multi-user MIMO (MU-MIMO) system based on the distributed antennas for 3GPP Long Term Evolution-Advanced (LTE-A). It is found that the existing methods presented...
This letter analyzes the bit error probability (BEP) performance of multiple-input/multiple-output (MIMO) systems employing maximal ratio transmission/maximal ratio combining (MRT/MRC) diversity in Rayleigh fading channels, where the channels are known at the both transmitter and receiver. An exact closed-from expression for the BEP performances of square and rectangular quadrature amplitude modulation...
