چکیده
In this paper we discuss the design of antenna arrays to be used for multiplexing applications. particular, introduce a suitable performance index analyze effect geometry and distribution users overall Multi-User Multiple Input Output systems. By means such index, can designed so as increase number multiplexed parallel sub-channels. Numerical results show that proper could allow double contemporary served system throughput.

Statistical antenna selection for spatial multiplexing systems
Spatial multiplexing is a signaling strategy for achieving high spectral efficiencies in communication links that employ multiple transmit and multiple receive antennas. In such systems it will be desirable to use only a subset of the available transmit and/or receive antennas to reduce cost and complexity. In this paper we address the problem of optimal antenna subset selection in spatial mult...
متن کاملTransmit Antenna Correlation in Spatial Multiplexing Systems
In this letter we present a transmit antenna correlation in spatial multiplexing systems with channel state information at the transmitter (CSIT) of a multiple-input multiple-output (MIMO) correlated channel. Indeed, high correlation degrades system capacity and performance. Most related work has thus far considered in the statistical channel model such as Kronecker model with an approximate To...
متن کاملPower Allocation for Dual Transmit Antenna Spatial Multiplexing Systems
In this paper, power allocation schemes for dual transmit multiple receive antenna communications is proposed and analyzed. Minimum error rate power allocation for a number of equalization schemes are proposed, including zero-forcing (ZF), successive interference cancellation (SIC) and ordered SIC (OSIC). It is shown both analytically and by numerical simulations that the proposed schemes impro...
متن کاملSpatial Multiplexing Gains for Realistic Sized Ad Hoc Networks with Directional Antenna Arrays
We concentrate on an ad hoc network model with nodes on integer lattice points over a 2D plane. We examine the limits of ad hoc network performance for systems with antenna arrays capable of allowing both spatial multiplexing and directional processing. Two cases are considered. In the first case, we consider “perfect” directional antenna arrays, in other words, each node can form beams of infi...
متن کاملTwo-Level Spatial Multiplexing using Hybrid Beamforming Antenna Arrays for mmWave Communications
In this work, we consider a two-level hierarchical MIMO antenna array system, where each antenna of the upper level is made up of a subarray on the lower one. The concept of spatial multiplexing is applied twice in this situation: Firstly, the spatial multiplexing of a Line-of-Sight (LoS) MIMO system is exploited. It is based on appropriate (sub-)array distances and achieves multiplexing gain d...
