چکیده
Massive multiple-input multiple-output (MIMO) is a profitable technique to greatly boost spectral efficiency, which has been embraced by the fifth-generation (5G) and sixth-generation (6G) mobile communication systems. By exploiting appropriate downlink precoding algorithms, base stations (BSs) equipped with large number of antennas are able provide service multiple users as well several cells at same time frequency. However, mutual coupling effect due compact antenna array gives misleading results in massive MIMO In this paper, we focus on for systems maximal ratio transmission (MRT), zero-forcing (ZF), regularize ZF (RZF), minimum mean square error (MMSE) solve problem. Additionally, construct closed-form expressions efficiency (SE) evaluate system performance. Simulation validate effectiveness proposed assessment method demonstrate significant impacts

On the Spectral Efficiency of Noncooperative Uplink Massive MIMO Systems
Massive multiple-input multiple-output (MIMO) systems have been drawing considerable interest due to the growing throughput demands on wireless networks. In the uplink, massive MIMO systems are commonly studied assuming that each base station (BS) decodes the signals of its user terminals separately and linearly while treating all interference as noise. Although this approach provides improved ...

We study the spectral efficiency (SE) of a mixedADC massive MIMO system in which K single-antenna users communicate with a base station (BS) equipped with M antennas connected to N high-resolution ADCs and M−N one-bit ADCs. This architecture has been proposed as an approach for realizing massive MIMO systems with reasonable power consumption. First, we investigate the effectiveness of mixed-ADC...
متن کاملThe Capacity of MIMO Wireless Systems with Mutual Coupling
MIMO wireless systems employing antenna arrays with close inter-element spacings exhibit a high degree of mutual coupling. In this case, the channel transfer matrix is a function of the matching network employed at transmit and receive. Existing capacity expressions are inappropriate, since the maximum mutual information will depend on antenna element loading. This paper develops a new expressi...
متن کاملSpectral and Energy Efficient Low-Overhead Uplink and Downlink Channel Estimation for 5G Massive MIMO Systems
Uplink and Downlink channel estimation in massive Multiple Input Multiple Output (MIMO) systems is an intricate issue because of the increasing channel matrix dimensions. The channel feedback overhead using traditional codebook schemes is very large, which consumes more bandwidth and decreases the overall system efficiency. The purpose of this paper is to decrease the channel estimation overhea...
متن کاملOn the energy/spectral efficiency of multi-user full-duplex massive MIMO systems with power control
In this paper, we consider a multi-user full-duplex (FD) massive multiple-input multiple-output (MIMO) system. The FD base station (BS) is equipped with large-scale antenna arrays, while each FD user is equipped with two antennas (one for transmission and the other one for reception). We assume that the channel state information (CSI) is imperfect, and no instantaneous CSI of loop interference ...
