Canceling Interferences for High Data Rate Time Reversal MIMO UWB System: A Precoding Approach

open access: yesEURASIP Journal on Wireless Communications and Networking, 2011
An ultra-high data rate time reversal (TR) multiple-input multiple-output (MIMO) ultra-wideband (UWB) communication system with space-time precoding is proposed.

Experimental Assessment of Different Receiver Structures for Underwater Acoustic Communications over Multipath Channels

open access: yesSensors, 2012
Underwater communication channels are often complicated, and in particular multipath propagation may cause intersymbol interference (ISI). This paper addresses how to remove ISI, and evaluates the performance of three different receiver structures and ...

Channel shortening algorithms for multiple intersymbol interference channels

open access: yes, 2016
We consider channel shortening (CS) algorithms for communication systems where multiple single antenna nodes are transmitting single carrier signals to a single antenna receiver over known intersymbol interference channels.

OFDM Signal Recovery in Deep Faded Erasure Channel

open access: yesIEEE Access, 2019
In high-speed digital wireless communication applications, the intersymbol interference channel may have spectral nulls or erasures, which may degrade the orthogonal frequency division multiplexing (OFDM) bit error rate (BER) performance.

Reduced-Complexity I/Q Turbo Detector for Convolutional-Coding Assisted Space-Time Trellis Coding

open access: yes, 2002
This paper presents a reduced-complexity turbo detector for convolutional-coding aided space-time trellis coded (STTC) schemes. The proposed technique is based on the separate in-phase/quadrature-phase (I/Q) detection principle developed for single ...
