A Secure Optimum Distributed Detection Scheme in Under-Attack Wireless Sensor Networks Abstract-We address the problem of centralized detection of a binary event in the presence of fraction falsi?able sensor nodes (SNs) (i.e., controlled by an attacker) for a bandwidth constrained under attack spatially uncorrelated distributed wireless sensor network (WSN). The SNs send their one-bit test…
Performance Analysis of OMP based Channel Estimations in Mobile OFDM Systems Abstract-To analyze the performance of orthogonal matching pursuit (OMP)-based compressed channel estimation (CCE) with deterministic pilot patterns, we propose a mathematical framework by de?ning four normalized mean-square-errors (NMSEs): the total NMSE (NMSE), the NMSE on dominant channel components (NMSEDT), the NMSE caused by ?lost…
