Uplink Multiuser MIMO Detection Scheme with Reduced Computational Complexity
The wireless communication systems with multiple antennas have recently received significant attention due to their higher capacity and better immunity to fading channels as compared to single antenna systems. A fast antenna selection scheme has been introduced for the uplink multiuser multiple-input multiple-output (MIMO) detection to achieve diversity gains, but the computational complexity o...
متن کاملLow Complexity Energy Efficient Uplink Multiuser Mimo
Energy efficiency is important for mobile devices because battery technology development has not kept up with the growing demand of ubiquitous broadband communications. This paper considered optimal energy-efficient design for uplink (UL) MUMIMO in a single cell environment. We first assume fixed amount of circuit power in all user. We show that some antennas should not be used even when their ...
متن کاملPerformance of Uplink Multiuser Massive MIMO Systems
We study the performance of uplink transmission in a large-scale (massive) MIMO system, where all the transmitters have single antennas and the receiver (base station) has a large number of antennas. Specifically, we analyze achievable degrees of freedom of the system without assuming channel state information at the receiver. Also, we quantify the amount of power saving that is possible with i...
متن کاملMultiuser SM-MIMO versus Massive MIMO: Uplink Performance Comparison
In this paper, we propose algorithms for signal detection in large-scale multiuser spatial modulation multipleinput multiple-output (SM-MIMO) systems. In large-scale SMMIMO, each user is equipped with multiple transmit antennas (e.g., 2 or 4 antennas) but only one transmit RF chain, and the base station (BS) is equipped with tens to hundreds of (e.g., 128) receive antennas. In SM-MIMO, in a giv...
متن کاملA Fair Scheduling Algorithm for Uplink Multiuser MIMO-OFDM System with MMSE-SIC detection
In this paper, we propose the new proportional fair (PF) scheduling algorithm for the uplink MIMO-OFDM systems. The proposed PF scheduling algorithm selects users based on the channel matrix to allocate spatial channels in a subband. Simulation results show that the proposed PF scheduling algorithm achieves better fairness and higher throughput than conventional scheduling algorithms. Index Ter...
