Transmit Antenna Selection for Multiple-Input Multiple-Output Spatial Modulation Systems

Multiple-input-multiple-output cooperative spatial modulation systems

In this study, the authors propose novel cooperative spatial modulation (SM) systems with two main relaying techniques [amplify-and-forward (AF) and decode-and-forward (DF)], where all nodes have multiple transmit and/or receive antennas. Most of the studies in the literature of cooperative SM systems, which combine the advantages of cooperative communications and SM systems, consider only the ...

Transmit Optimization for Multicarrier and Multiple - Input Multiple - Output Wireless

To meet growing demand for wireless access to voice, data and multimedia services, current wireless communication technologies need further improvement in spectral efficiency. Many enabling technologies have been proposed, including multicarrier modulation, multiple-input multiple-output (MIMO) and link adaptation. This thesis investigates link adaptation, particularly transmit optimization in ...

Multiple-Input Multiple-Output Wireless Systems: Coding, Distributed Detection and Antenna Selection

A Multiband Multiple-input Multiple-output Antenna System for Long Term Evolution and Wireless Local Area Networks Handsets

A novel multiband multiple-input-multiple-output (MIMO) antenna system is proposed. The MIMO antenna system consists of two antenna elements, each of which comprises of three radiators: a driven monopole, an S-shaped strip and an inverted F-shaped strip and occupies footprint of 15x18.5x0.8 mm3 only. The driven monopole acts as a quarter-wave monopole and stimulate higher mode resonance. The tw...

Minimum BER Transmit Power Allocation and Beamforming for Two-Input–Multiple-Output Spatial Multiplexing Systems

A two-input–multiple-output (TIMO) system represents an important special case of multiple-input–multiple-output (MIMO) systems in practical scenarios. In this paper, transmit optimization for TIMO spatial multiplexing systems is investigated. Minimum bit-error rate (MBER) is employed as the optimization criterion. Approximate MBER transmit power allocation for a variety of receiver structures ...
