Reduced-Dimension Multiuser Detection [PDF]
IEEE Transactions on Information Theory, 2010 We present a reduced-dimension multiuser detector (RD-MUD) structure for synchronous systems that significantly decreases the number of required correlation branches at the receiver front-end, while still achieving performance similar to that of the conventional matched-filter (MF) bank.

Reduced-dimension space-time adaptive processing for airborne radar with co-prime array
The Journal of Engineering, 2019 Space-time adaptive processing (STAP) for airborne radar with co-prime arrays is shown to have excellent superiority compared to traditional STAP with uniform linear array radar.

Data‐dependent reduced‐dimension STAP
IET Radar, Sonar and Navigation, 2019 Space‐time adaptive processing (STAP) is supposed to be a key technique for detection of slow‐moving targets in airborne radar applications. To overcome the difficulties of obtaining lots of independent and identical distributed secondary data samples, many sub‐optimal STAP algorithms are proposed such as reduced‐dimension STAP, reduced‐rank STAP, or ...

An Efficient Sparse Bayesian Learning STAP Algorithm with Adaptive Laplace Prior
Remote Sensing, 2022 Space-time adaptive processing (STAP) encounters severe performance degradation with insufficient training samples in inhomogeneous environments. Sparse Bayesian learning (SBL) algorithms have attracted extensive attention because of their robust and ...

Magnetism in reduced dimensions [PDF]
Comptes Rendus. Physique, 2005 We propose a short overview of a few selected issues of magnetism in reduced dimensions, which are the most relevant to set the background for more specialized contributions to the present Special Issue. Magnetic anisotropy in reduced dimensions is discussed first, on a theoretical basis, then with experimental reports and views from surface to single ...

Reduced dimension MAP turbo-BLAST detection [PDF]
2004 IEEE 59th Vehicular Technology Conference. VTC 2004-Spring (IEEE Cat. No.04CH37514), 2005 The Bell Labs layered space-time (BLAST) architecture is a simple and efficient multiantenna coding structure that can achieve high spectral efficiency. Many BLAST detectors require more receiver antennas than transmitter antennas. We propose two novel turbo-processing BLAST detectors that can operate in systems with fewer receiver antennas than ...
