Pilot Signal Design for Massive MIMO Systems: A Received Signal-To-Noise-Ratio-Based Approach

open access: yes, 2014
In this paper, the pilot signal design for massive MIMO systems to maximize the training-based received signal-to-noise ratio (SNR) is considered under two channel models: block Gauss-Markov and block independent and identically distributed (i.i.d ...

On balanced incomplete block designs with specified weak chromatic number

open access: yes, 2013
A weak $c$-colouring of a balanced incomplete block design (BIBD) is a colouring of the points of the design with $c$ colours in such a way that no block of the design has all of its vertices receive the same colour.

pH-Degradable mannosylated nanogels for dendritic cell targeting [PDF]

open access: yes, 2016
We report on the design of glycosylated nanogels via core-cross linking of amphiphilic non-water-soluble block copolymers composed of an acetylated glycosylated block and a pentafluorophenyl (PFP) activated ester block prepared by reversible addition ...

Cyclic Block Designs With Block Size 3

open access: yesEuropean Journal of Combinatorics, 1981
We prove that the necessary conditions for the existence of cyclic block designs with block size 3 are sufficient with two exceptions.

Advanced Design of Block Shear Failure

open access: yesMetals, 2021
This paper presents the behaviour and design procedure of bolted connections which tend to be sensitive to block shear failure. The finite element method is employed to examine the block shear failure.

Computing centroids in current-mode technique [PDF]

open access: yes, 1993
A novel current-mode circuit for calculating the centre of mass of a discrete distribution of currents is described. It is simple and compact, an ideal building block for VLSI analogue IC design.

On block designs with repeated blocks

open access: yesDiscrete Mathematics, 1992
This paper is concerned with balanced incomplete block designs in which repeated blocks are allowed. If \({\mathcal D}\) is such a \((v,k,\lambda)\)- design (using the standard notation), let \(b^*\) denote the number of distinct blocks. Let \(BIBD(v,k,\lambda| b^*)\) denote the family of all such designs \({\mathcal D}\). Fixing the number of points \(

Blocking Sets in Designs with Block Size 4

open access: yesEuropean Journal of Combinatorics, 1990
Constructions are given which produce block designs with \(\lambda=1\) or 2 and \(k=4\) admitting a blocking set. The construction includes all admissible orders \(n\) with \(\lambda=1,2\) and \(k=4\) except 8 cases. There are four separate constructions, one for \(\lambda=1\) and \(n\equiv1\) mod 12, one for \(\lambda=1\) and \(n\equiv 4\) mod 12, one

Decoding Brain Signals from Rapid-Event EEG for Visual Analysis Using Deep Learning

open access: yesSensors
The perception and recognition of objects around us empower environmental interaction. Harnessing the brain’s signals to achieve this objective has consistently posed difficulties.

Extension of SBL Algorithms for the Recovery of Block Sparse Signals with Intra-Block Correlation

open access: yes, 2014
We examine the recovery of block sparse signals and extend the framework in two important directions; one by exploiting signals' intra-block correlation and the other by generalizing signals' block structure.
