Multiple-input multiple-output (MIMO) technology is maturing and is being incorporated into emerging wireless broadband standards like long-term evolution (LTE) [1. [] Key Result The gains in multiuser systems are even more impressive, because such systems offer the possibility to transmit simultaneously to several users and the flexibility to select what users to schedule for reception at any given point in time [2].

Pairing and Scheduling for Large Array MIMO Using Regularized Channel Inversion Receivers Over Nakagami-m Fading
This Paper focuses on the efficiency of the throughput and fairness of large MIMO, which makes a clean break with current practice through the use of a very large number of service antennas that are operated fully coherently and adaptively.
Massive MIMO Communications
The basics of massive MIMO are described and how it will satisfy the high‐data‐rate demands of 5G cellular systems for frequency bands up to 100 GHz.
Evaluation of precoding and feedback quantization schemes for multiuser communications systems
This thesis is primarily focused on improving the efficiency of precoding implementations and the performance of feedback schemes in MU-MISO systems, and reveals that zero-forcing, Tomlinson-Harashima precoding (THP) and lattice reduction (LR) are the most suitable techniques for covering the entire range of performance and computational complexity.

This paper investigates how much standard linear precoders help the ISI mitigation by shortening the rms delay spread, and measures a massive MIMO channel with 128 antennas at the base station and 36 users, including 26 line-of-sight and 10 non line- of-sight.
Efficient Processing and Storage for Massive MIMO Digital Baseband
The energy-efficient computing and data organization of large matrices provides a promising methodology for the actual deployment of massive MIMO baseband processor, and a resource scheduling scheme to switch between accurate and approximative algorithms is developed to exploit the dynamics in the wireless channel.
Advanced modulation techniques for scaling up multiuser MIMO communications
The results suggest that an expense in complexity is not the only way to improve error performance, but near-optimal reliability is also possible using simple techniques through a reduction in the multiplexing gain.

This dissertation presents an overview of theoretical concepts of MIMO systems, and SISO transmission and reception techniques have been considered to refine the synchronization (with 16-QAM), thus facilitating the future implementation of the MIMo system.

This paper addresses digital communication in a Rayleigh fading environment when the channel characteristic is unknown at the transmitter but is known (tracked) at the receiver with the aim of leveraging the already highly developed 1-D codec technology.

A cellular base station serves a multiplicity of single-antenna terminals over the same time-frequency interval and a complete multi-cellular analysis yields a number of mathematically exact conclusions and points to a desirable direction towards which cellular wireless could evolve.
On the asymptotic capacity of MIMO systems with antenna arrays of fixed length
For many channel correlation structures, it is demonstrated that the asymptotic performance converges almost surely, implying that such MEA systems have a certain strong robustness to the instantiation of the channel fading values.
A stochastic MIMO radio channel model with experimental validation
A simple stochastic MIMO model channel has been developed that uses the correlation matrices at the mobile station (MS) and base station (BS) so that results of the numerous single-input/multiple-output studies that have been published in the literature can be used as input parameters.

An overview of approaches for detection for MIMO, in the communications receiver context, finds that notions that are important in slow fading are less important in fast fading, where diversity is provided anyway by time variations.
