A locally repairable code (LRC) is a $[n, k, d]$ linear code with length $n$ , dimension $k$ , minimum distance $d$ and locality $r$ , which means that every code symbol can be repaired by at most $r$ other symbols. LRCs have become an important cand

We propose a weighted $l_{p}$ minimization method for downlink channel estimation in frequency division duplexing massive multiple-input multiple-output (MIMO) systems. The proposed algorithm involves two stages, in which it first diagnoses the downl

When the complex least mean-square (CLMS) algorithm is used to estimate a complex sparse system, its convergence rate is relatively slow. To make full use of the sparsity of the unknown system to improve convergence rate, a zero-attracting CLMS (ZA-C

Texture is widely existed in various images and plays an important role in many area such as medical image diagnosis, remote sensing, etc. However, the image in texture regions is tend to be deteriorated during restoration process. In this paper, we

In this paper, an efficient finger vein recognition algorithm based on the combination of the nearest centroid neighbor and sparse representation classification techniques ( ${k}$ NCN-SRC) is presented. The previously proposed recognition algorithms

In this paper, a new direction-of-arrival (DOA) estimation method based on multiple Toeplitz matrices reconstruction is proposed for coherent narrowband signals with a uniform linear array (ULA). First, the received signals impinging on the ULA are r

In this paper, we analyse the performance of physical layer security over Fluctuating Beckmann (FB) fading channel which is an extended model of both the $\kappa-\mu$ shadowed and the classical Beckmann distributions. Specifically, the average secrec

In this paper, the target node localization problems based on hybrid RSS-AOA measurements in both noncooperative and cooperative three-dimensional (3-D) wireless sensor networks (WSNs) are discussed. By using novel error approximate expressions for b

Given Y ∈ Rm×I and A ∈ Rm×n, the multiple measurement vector (MMV) problem aims to recover the support of the K-row sparse matrix X from Y = AX + E. In this paper, we present a sufficient condition for exact support recovery of K-row sparse mat
