MIMO communications based on molecular diffusion

2012 IEEE Global Communications Conference (GLOBECOM), 2012
Diffusion-based communication refers to the transfer of information using molecules as message carriers whose propagation is based on the law of molecular diffusion. Path loss can have a major impact on the link quality in molecular communication as the signal strength is shown inversely proportional to the cube of the communication distance.

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.

Uniform channel decomposition for MIMO communications

IEEE Transactions on Signal Processing, 2005
Assuming the availability of the channel state information at the transmitter (CSIT) and receiver (CSIR), we consider the joint optimal transceiver design for multi-input multi-output (MIMO) communication systems. Using the geometric mean decomposition (GMD), we propose a transceiver design that can decompose, in a strictly capacity lossless manner, a ...

MIMO for airborne communications [Industry Perspectives]

IEEE Wireless Communications, 2014
MIMO technology has been widely applied in terrestrial wireless communications due to its high spectral efficiency in the presence of rich multi-paths. The benefits of MIMO in airborne communications, however, have not been fully recognized. The lack of scattering in the airborne environment may lead one to incorrectly believe that the spectral ...

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.

Multistratum-permutation codes for MIMO communication

IEEE Journal on Selected Areas in Communications, 2003
Multiple-input-multiple-output (MIMO) systems offer much capacity gain over single antenna approaches. The recently proposed multistratum space-time code (MSSTC) is such a MIMO-scheme among many others. In this paper, a generalization of the multistratum idea is presented and leads to the new family of multistratum-permutation codes.

MIMO equalization for helicopter-to-ground communications

2011 - MILCOM 2011 Military Communications Conference, 2011
Multiple-input/multiple-output (MIMO) channel models derived from channel sounding experiments conducted at Cairns Army Airfield, Ft. Rucker, AL are used to assess MIMO equalizers based on time-reversal space-time block codes (TR-STBC). For the channels used in this case study, 2 × 1 MIMO equalizer offers an improvement of 0.75 dB to 1.5 dB relative to

The Analysis of MIMO Communication

Applied and Computational Engineering
Communication technologies have developed fast from the First Generation (1G) of mobile communication networks to the Fifth (5G) in 40 years. However, they cannot meet the growing communication requirements of exponentially increasing connected devices. To support these requirements, Multiple-Input Multiple-Output (MIMO) technology has gained extensive
