Diffusive MIMO Molecular Communications: Channel Estimation, Equalization and Detection

open access: yes, 2019
In diffusion-based communication, as for molecular systems, the achievable data rate is low due to the stochastic nature of diffusion which exhibits a severe inter-symbol-interference (ISI). Multiple-Input Multiple-Output (MIMO) multiplexing improves the

MIMO Communications in Ad Hoc Networks [PDF]

open access: yes2005 IEEE 61st Vehicular Technology Conference, 2005
We consider MIMO (multiple-input multiple output) communications in an ad hoc network with K simultaneous communicating transceiver pairs. In particular, we compare channelized MIMO transmission and the MIMO interference transmission using the inherent multiplexing gain of multiple transmit/receive antennas.

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems

open access: yesAdvanced Electronic Materials, EarlyView.
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Joint parameter estimation employing coherent passive MIMO radar

open access: yesThe Journal of Engineering, 2019
Passive multiple-input multiple-output radar is studied for the problem of joint estimation of target location and velocity. A general case is considered, where the signals of opportunity may be non-orthogonal and the clutter-plus-noise may be correlated.
