Sub-optimal initialization for blind equalization with fast convergence in OFDM/OQAM modulation

This paper deals with blind equalization in orthogonal frequency division multiplexing/offset quadrature amplitude modulation (OFDM/OQAM) systems. Blind equalization is an interesting solution with regard to the spectral efficiency since no pilot is used for the signal recovering, but blind iterative…

Sum-MSE minimization for MIMO interference channels under CSI mismatch

This paper considers multiple-input multiple-output (MIMO) interference channels, where the robust transceiver is designed under imperfect channel state information (CSI). Our objective is to minimize the sum mean-square-error (MSE) subject to per-transmitter power constraints. An iterative algorithm is proposed to…

Sparse Uncorrelated Linear Discriminant Analysis for Undersampled Problems

Linear discriminant analysis (LDA) as a well-known supervised dimensionality reduction method has been widely applied in many fields. However, the lack of sparsity in the LDA solution makes interpretation of the results challenging. In this paper, we propose a new…

Band anticrossing and luminescence emission in dilute InAs1−x−yNxSbyquaternary alloys

In this paper, we calculate the luminescence of the dilute quaternary InAs1−x−yNxSby semiconductor using a microscopic approach. The theory starts with the band anticrossing model applied to both conduction and the valence band to generate input for analytical approximations that lead…

Analysis on the LSP and shell modes of a silver-strip plasmonic nanolaser

We consider the two-dimensional (2-D) problem of the H-polarized electromagnetic eigenmodes that can exist on a silver nanostrip placed in the centre of an active shell in the form of circular quantum wire (QW). Both the lasing mode frequency and…

Asymmetric transmittance of the surface plasmon-polariton +1 Bragg beams

We investigate theoretically the propagation of a surface plasmon polariton(SPP) propagating along the metal/air interface where metallic part consists of two metallic sections with a periodically modulated interface between them. We find that such a structure exhibits asymmetric transmittance for…

Alternative Multiview Maximum Entropy Discrimination

Maximum entropy discrimination (MED) is a general framework for discriminative estimation based on maximum entropy and maximum margin principles, and can produce hard-margin support vector machines under some assumptions. Recently, the multiview version of MED multiview MED (MVMED) was proposed.…

Dual secured hybrid image watermarking in wavelet and singular domain

These days there is an increased risk of copyright violation of multimedia data that has become an important issue for content owners and service providers. Watermarking technology aims at asserting Intellectual Property Rights (IPR) of digital images by inserting a…

Stretchy multivariate polynomial classification

A stretchy classification methodology adopting multivariate polynomials is proposed in this paper. Through minimization of an approximated p-norm of the parameter vector subject to classification error constraints, an approximated minimum norm solution in dual form is derived for under-determined systems.…

1.31 µm quantum-dot hybrid mode-locked lasers for optical time-division multiplexing

We report on jitter reduction and frequency tuning ability of 1.31 µm 40 GHz quantum-dot mode-locked lasers with the main focus on hybrid mode locking. The frequency of the external electrical source is usually chosen to be close to the…
