Performance 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 کاملDistance-Aware Beamforming for Multiuser Secure Communication Systems
Typical cryptography schemes are not well suited for low complexity types of equipment, e.g., Internet of things (IoT) devices, as they may need high power or impose high computational complexity on the device. Physical (PHY) layer security techniques such as beamforming (in multiple antennas systems) are possible alternatives to provide security for such applications. In this paper, we consid...
متن کاملStepwise Transmit Antenna Selection in Downlink Massive Multiuser MIMO
Due to the large power consumption in RF-circuitry of massive MIMO systems, practically relevant performance measures such as energy efficiency or bandwidth efficiency are neither necessarily monotonous functions of the total transmit power nor the number of active antennas. Optimal antenna selection is however computationally infeasible in these systems. In this paper, we propose an iterative ...
متن کاملMassive multiuser MIMO downlink with low-resolution converters
In this review paper, we analyze the downlink of a massive multiuser multiple-input multiple-output system in which the base station is equipped with low-resolution digital-to-analog converters (DACs). Using Bussgang’s theorem, we characterize the sum-rate achievable with a Gaussian codebook and scaled nearestneighbor decoding at the user equipments (UE). For the case of 1bit DACs, we show how ...
