Parallel interference cancellation based turbo space-time equalization in the SDMA uplink

open access: yes, 2007
A novel Parallel Interference Cancellation (PIC) based turbo Space Time Equalizer (STE) structure designed for multiple antenna assisted uplink receivers is introduced. The proposed receiver structure allows the employment of non-linear type of detectors

Dimmable constant weight polar‐coded non‐orthogonal multiple access with orthogonal space‐time block coding visible light communication systems

open access: yesIET Communications, Volume 18, Issue 17, Page 1071-1078, October 2024.
The study integrates dimmable constant weight polar‐coded non‐orthogonal multiple access (CWPC‐NOMA) with orthogonal space‐time block coding (OSTBC) for visible light communication (VLC). The proposed scheme enhances spectral efficiency and reliability while optimizing resource utilization and leveraging transmit diversity.

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 ...

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 ...

Asymptotic Bayesian Decision Feedback Equalizer Using a Set of Hyperplanes

open access: yes, 2000
We present a signal space partitioning technique for realizing the optimal Bayesian decision feedback equalizer (DFE). It is known that, when the signal to noise ratio (SNR) tends to infinity, the decision boundary of the Bayesian DFE is asymptotically ...

Reduced Complexity I/Q Turbo Detection for Space-Time Trellis-Coded Systems

open access: yes, 2004
A reduced-complexity turbo-detection scheme, referred to here as the R-TD arrangement, is proposed for employment in space-time trellis-coded (STTC) systems using the inphase/quadrature-phase (I/Q) cancellation technique that was previously developed for

Joint multi-user detection and intersymbol interference cancellation for WCDMA satellite UMTS [PDF]

open access: yes, 2003
In this work we present two different intersymbol interference (ISI) cancellation systems, namely the commutation signaling (CS) and orthogonal code-division transmit diversity (O-CDTD) in combination with satellite path diversity, which leads to a high ...
