Suboptimal greedy power allocation schemes for discrete bit loading [PDF]
, 2013 In this paper we consider low cost discrete bit loading based on greedy power allocation (GPA) under the constraints of total transmit power budget, target BER, and maximum permissible QAM modulation order.

On performance of greedy algorithms
Journal of Approximation Theory, 2011 Let \(H\) be a Hilbert space and \(\mathcal{D}:=\{\varphi_{i}:i\in\mathbb{N} \}\subset H\) be such that \(\overline{\text{span}\mathcal{D}}\mathcal{=}H.\) A dictionary \(\mathcal{D}\) is called \(M\)-coherent if its coherence, defined by \(\sup\{|| :\varphi,\psi\in\mathcal{D}, \varphi\neq\psi\}\) is exactly \(M.\) The authors consider the Orthogonal ...

Semisoft Generalized Total Variation Minimization for Image Reconstruction in Computed Tomography
IEEE Access, 2017 The generalized l1 greedy algorithm was recently proposed and shown to outperform the standard reweighted l1-minimization and l1-greedy algorithms for image reconstruction in computed tomography (CT).
