Closed-Form Capacity Reliability Analysis of Multiuser MIMO System in the Presence of Generalized Multipath Fading

Abstract

This research studies the problem of a joint capacity/capacity reliability analysis of the multiuser multi-input multioutput (MIMO) system functioning in the presence of generalized multipath fading. The study presents the derived results of the closed-form analytical statistical description of the ergodic sum-rate capacity, the capacity reliability and the capacity’s higher-order statistics in the case of complex Nakagami-m distributed channel transmission coefficients. A numerical verification of the derived expressions was performed, and it demonstrated excellent correspondence with the simulation. The system performance was evaluated with the help of a numerical analysis of the joint first- and second-order statistics description, depending on the channel and system parameters. The results demonstrated several peculiarities, e.g., the existence of a specific extremum of the capacity reliability for small-sized MIMO systems, its opposite behavior (in terms of the varying number of antenna elements) for heavy and light fading, and the existing asymptotic regions of the system and the channel parameters.

Low-Profile UWB-MIMO Antenna System with Enhanced Isolation Using Parasitic Elements and Metamaterial Integration

“…UWB technology has received significant attention since 2002, when the Federal Communications Commission (FCC) regulated its utilization for commercial, unlicensed applications over the frequency band of 3.1-10.6 GHz in the United States [3,4]. This technology faces some challenges, such as multipath fading, channel capacity, and the bit error rate [5]. MIMO technology, which makes use of multiple antennas, provides a solution for the multipath effect and increasing the channel capacity without the need for an additional frequency spectrum or transmitted power [6].…”

Two Elements Orthogonally Placed UWB-MIMO for RADAR, Satellite and Terrestrial Communications

“…Several UWB antenna designs with basic geometric shapes like rectangles, circles, ellipses, polygons and exponential curves or a mix of these [14][15][16][17][18], P shape monopole antenna with multimode resonator band pass filter [19], hexagonal slot in a rectangular step shape patch with partial ground plane [20], grain rice shape antenna with split ring resonator [21], jug-shaped radiator fed by a coplanar waveguide (CPW) technique [22], circular ring monopole antenna with semi-circular stubs to enhance the bandwidth [23]. These designed systems are vulnerable to the impact of the multipath fading effect, reliability, and data quality, this effect will be minimized by using MIMO Antenna [24]. Since mutual coupling is a result of electromagnetic interactions, due to several antenna elements can be used in the MIMO system.…”
