Exciting recent developments in wireless multiantenna communications have led to designs aiming mainly at one of two objectives: either high-performance by enabling the diversity provided by multi-input multi-output (MIMO) channels or high-rates by capitalizing on space-time multiplexing gains to realize the high capacity of MIMO fading channels. By concatenating a linear complex-field coder (a...

This paper addresses the design and implementation of multi-input multi-output (MIMO) fuzzy control for mobile robot. Firstly, MIMO fuzzy control is apply to track different desired trajectories. Secondly, the controller performs on robot for navigation purpose to avoid obstacles and reach defined target. The proposed MIMO fuzzy controller was investigated based on several conducted MATLAB simu...

Next generation of wireless networks will likely rely on large-scale antenna systems, either in the form of massive multi-input-multi-output (MIMO) or millimeter wave (mmWave) systems. Therefore, the conventional fully-digital precoders are not suitable for physical layer multicasting as they require a dedicated radio frequency chain per antenna element. In this paper, we show that in a multi-g...

Hailed as a very important breakthrough in recent times, multiple antenna systems, also called as multiple input multiple output (MIMO) systems have been shown to have enormous gains over conventional systems in point-to-point scenarios for both wireless and wire-line environments. A very important litmus test for the real promise of MIMO systems is in their performance in multi-user scenarios....

We compare the achievable throughput of time division multiple access multiple-input multiple output (TDMAMIMO) scheme illustrated in 3rd generation partnership project (3GPP) MIMO technical report (TR), versus the sum-rate capacity of a space-time multiple access (STMA). These schemes have been proposed to improve 3GPP high speed downlink packet access (HSDPA) channel by employing multiple ant...

Multiple-Input Multiple-Output (MIMO) wireless communication system, which is also called Multiple-Antenna system, is well known as one of the most important technologies and widely studied nowadays (Winters, 1987; Foschini & Gans, 1998; Marzetta & Hochwald, 1999; Raleigh & Cioffi, 1998). The main idea of MIMO wireless communication is to utilize the spatial degree of freedom of the wireless mu...

Millimeter wave (mmWave) communication by utilizing lens antenna arrays is a promising technique for realizing cost-effective 5G wireless systems with large MIMO (multiple-input multiple-output) but only limited radio frequency (RF) chains. This paper studies an uplink multi-user mmWave single-sided lens MIMO system, where only the base station (BS) is equipped with a full-dimensional (FD) lens...

The average channel capacity and the SINR distribution for multiuser Multiple Input Multiple Output (MIMO) systems in combination with the base station based packet scheduler are analyzed in this paper. The packet scheduler is used to exploit the available multiuser diversity in all the three physical domains (i.e., space, time and frequency). The analysis model is based on the generalized 3GPP...

This paper presents a brief overview of spacetime algorithms for communication systems operating in quasi-static Rayleigh flat fading environments. The space-time algorithms exploit a multi-input multi-output (MIMO) channel and are designed to meet criteria for optimality under three different channel state information (CSI) conditions: 1) CSI at receiver and transmitter, 2) CSI at receiver but...
