Sparsity regularized recursive total least-squares
(Academic Press Inc Elsevier Science, 2015)
This paper introduces a new family of recursive total least-squares (RTLS) algorithms for identification of sparse systems with noisy input vector. We regularize the RTLS cost function by adding a sparsifying term and ...
MRI reconstruction with joint global regularization and transform learning
(Pergamon-Elsevier Science Ltd, 2016)
Sparsity based regularization has been a popular approach to remedy the measurement scarcity in image reconstruction. Recently, sparsifying transforms learned from image patches have been utilized as an effective regularizer ...
LDPC Code Design for the Two-User Gaussian Multiple Access Channel
(Ieee-Inst Electrical Electronics Engineers Inc, 2016)
We study code design for two-user Gaussian multiple access channels (GMACs) under fixed channel gains and under quasi-static fading. We employ low-density parity-check (LDPC) codes with BPSK modulation and utilize an ...
Implementing the Han-Kobayashi Scheme Using Low Density Parity Check Codes Over Gaussian Interference Channels
(Ieee-Inst Electrical Electronics Engineers Inc, 2015)
We focus on Gaussian interference channels (GICs) and study the Han-Kobayashi coding strategy for the two-user case with the objective of designing implementable (explicit) channel codes. Specifically, low-density parity-check ...
