Single Carrier Modulation With Nonlinear Frequency Domain Equalization: An Idea Whose Time Has Come—Again
TL;DR: This tutorial paper aims at providing an overview of nonlinear equalization methods as a key ingredient in receivers of SCM for wideband transmission, and reviews both hybrid (with filters implemented both in time and frequency domain) and all-frequency-domain iterative structures.
Journal ArticleDOI
RSS-Based Localization in Wireless Sensor Networks Using Convex Relaxation: Noncooperative and Cooperative Schemes
TL;DR: New approaches based on convex optimization to address the received signal strength (RSS)-based noncooperative and cooperative localization problems in wireless sensor networks (WSNs) are proposed by using an array of passive anchor nodes to collect noisy RSS measurements from radiating source nodes in WSNs.
Proceedings ArticleDOI
A multiple access scheme for the uplink of broadband wireless systems
TL;DR: By employing IB-DFE (iterative block decision feedback equalization) techniques, this work can have detection performances close to the matched filter bound, and even for fully loaded systems and severe time-dispersive channels.
Journal ArticleDOI
3-D Target Localization in Wireless Sensor Networks Using RSS and AoA Measurements
TL;DR: A novel nonconvex estimator is derived based on the least squares criterion based on range and angle measurement models, and it is shown that the developed estimator can be transformed into a generalized trust region subproblem framework, by following the squared range approach, for noncooperative WSNs.
Proceedings ArticleDOI
Comparison of two modulation choices for broadband wireless communications
TL;DR: In this paper, a comparison of single-carrier (SC) and multicarrier (MC) modulation schemes for broadband wireless communications is presented, by considering a similar frequency-domain equalization in both cases, and then by adding the impact of channel coding and amplification issues.
