MIMO time reversal communications

Proceedings of the second workshop on Underwater networks - WuWNet '07, 2007
A time reversal mirror (TRM) exploits spatial diversity to achieve spatial and temporal focusing, a useful property for communications in an environment with significant multipath. Temporal focusing (pulse compression) mitigates intersymbol interference (ISI) while spatial focusing enables a straightforward extension to multiple-input/multiple-output ...

MIMO delay-limited communications

TENCON 2007 - 2007 IEEE Region 10 Conference, 2007
An important problem for delay-limited communications requires to minimize the required transmit power for ensuring an acceptable outage probability for a given number of blocks transmission. In this paper, we consider a multiple-input multiple-output (MIMO) Rayleigh block flat-fading channel and investigate the joint optimization of power allocation ...

SDD-MIMO: Ubiquitous Embedded MIMO for Community Broadband

2018 International Conference on Computing, Engineering, and Design (ICCED), 2018
Multi-user and massive or large-scale MIMO have proven very effective customer access technologies for serving multiple users on the same frequency resource. However the technological cost and complexity of large scale cellular deployments to sparsely populated areas makes them unsuitable for deployment by individuals or the communities themselves.

Networked Optical Massive MIMO Communications

IEEE Transactions on Wireless Communications, 2020
The low cost and versatility of optical devices make it possible to pack a large number of optical transceivers into arrays and exploit massive multiple-input multiple-output (MIMO) transmission in optical wireless communications. Nevertheless, optical massive MIMO presents several distinct challenges such as, the line-of-sight propagation and ...

Optical wireless MIMO communications (OMIMO)

IEEE Global Telecommunications Conference, 2004. GLOBECOM '04., 2005
We propose optical wireless multiple-input multiple-output (OMIMO) communications to achieve high speed transmission with a compact transmitter and receiver. In OMIMO, by using zero forcing (ZF), we can eliminate the other signal interferences transmitted from other optical transmit antennas.

Energy-efficient MIMO SVD communications

2012 IEEE 23rd International Symposium on Personal, Indoor and Mobile Radio Communications - (PIMRC), 2012
Multiple-input multiple-output (MIMO) techniques can be used for reducing the energy consumption of wireless communications. Although some research has been reported on this topic, the rules by which the MIMO physical layer parameters should be chosen in order to achieve energy efficiency have not yet been formally established.
