Abstract In this letter, a new learnable binary MIMO detection algorithm in massive MIMO systems with one‐bit analog‐to‐digital converters is proposed. A negative penalty is introduced to transform a non‐convex constraint to a convex box cons

This paper considers the intelligent reflecting surface-aided MIMO secrecy rate maximization. We apply the alternating optimization to maximize the secrecy rate of the MIMO wiretap channels. We first provide the closed-form solution to each subproble

We consider MIMO systems with self-sustainable intelligent reflecting surface (IRS), where IRS can harvest energy from received power. We characterize the achievable region of rate-energy pairs and propose an alternating optimization algorithm to try

In this paper, we propose an accelerated sparse recovery algorithm based on inexact alternating direction of multipliers. We formulate a sparse recovery problem with a concave regularizer and solve it with the relaxed and accelerated alternating meth

As components get closer together and more devices are integrated into a package, electromagnetic interference (EMI) is one of the most common concerns to be addressed. EMI shielding is not a new topic and its technology has widely been applied to co

In this paper, we propose element-wise adaptive threshold methods for learned iterative shrinkage thresholding algorithms. The threshold for each element is adapted in such a way that it is set to be smaller when the previously recovered estimate or

In this paper, we study transmission strategies for hybrid free space optical (FSO)/radio frequency (RF) systems by jointly considering link selection, power allocation, and reliability guarantees. Specifically, under an explicit long-term average re
