On equivalence of SLNR-based precoding and RBD precoding
Electronics Letters, 2012 Signal-to-leakage-plus-noise ratio (SLNR) based precoding and regularised block diagonalisation (RBD) precoding are two notable linear precoding schemes in downlink multi-user multiple-input multiple-output (MIMO) systems. The equivalence of these two precoding schemes is demonstrated.

MIMO Relay Network With Precoding [PDF]
IEEE Communications Letters, 2016 We study the achievable rate in a MIMO, dual-hop, relay network where source and relay nodes may precode their input signals before transmission. Although an iterative expression for optimal precoders in this scenario is available in the literature, the corresponding achievable rate cannot be obtained analytically.

Trade-off between complexity and BER performance of a polynomial SVD-based broadband MIMO transceiver [PDF]
, 2010 In this paper we investigate non-linear precoding solutions for the problem of broadband multiple-input multiple output(MIMO) systems. Based on a polynomial singular value decomposition (PSVD) we can decouple a broadband MIMO channel into independent ...

A transceiver design based on uniform channel decomposition and MBER vector perturbation [PDF]
, 2010 Uniform channel decomposition (UCD), as an improvement of geometric mean decomposition (GMD), is capable of decomposing a multiple-input–multiple-output (MIMO) channel into multiple subchannels having an identical capacity.

Epilepsia, EarlyView.Abstract Objective In temporal lobe epilepsy (TLE), patients often present with neurobehavioral comorbidities encompassing affective and cognitive difficulties. Whereas the latter have been related to atypical connectivity of mesiotemporal and frontotemporal circuits, the brain basis of affective symptoms remains incompletely understood.

Spectrally Precoded OFDM [PDF]
IEEE Transactions on Communications, 2006 By bilinearly transforming the rectangularly pulsed multicarrier basis signals, new basis sets containing full-response continuous basis signals are developed for constructing spectrally efficient orthogonal frequency-division multiplexing (OFDM) signals with or without cyclic prefix (CP) or zero padding (ZP).
