Multi-channel Two-Way Time of Flight Sensor Network Ranging
Two-way time of flight (ToF) ranging is one of the most interesting approaches for localization in wireless sensor networking since previous ToF ranging approaches using commercial off-the-shelf (COTS) devices have achieved good accuracy. The COTS-based approaches were, however, evaluated only in line-of-sight conditions. In this paper, we extend ToF ranging using multiple IEEE 802.15.4 channel...
متن کاملAn Outer Bound for a Multiuser Two-Way Channel
Most networks are two-way in nature, i.e., senders are also receivers. However, little is known about two-way networks except for the simplest two-way channel between two nodes, first proposed and studied by Shannon in 1961. In this paper, we continue our study of a three-node multiuser two-way channel first proposed by the authors in [1]. Our main result is an outer bound on the capacity regio...
متن کاملDistributed Multiuser Two-Way AF Relaying Systems under Jamming Environment
A distributed multiuser two-way amplify-and-forward (AF) wireless relay strategy consisting of 2M sources (or 2M destinations) and N relays all equipped with single antenna per communication node is studied in this paper. All sources act as both sources and destinations with a self-interference cancelation process at the 2M destinations. The main objective is to design the closed-form of minimu...
متن کاملSimultaneous Two-Way Clustering of Multiple Correspondence Analysis.
A 2-way clustering approach to multiple correspondence analysis is proposed to account for cluster-level heterogeneity of both respondents and variable categories in multivariate categorical data. Specifically, in the proposed method, multiple correspondence analysis is combined with k-means in a unified framework in which k-means is applied twice to partition the object scores of respondents a...
متن کاملMultiuser Interference Mitigation in Noncoherent UWB Ranging via Nonlinear Filtering
Ranging with energy detectors enables low-cost implementation. However, any interference can be quite detrimental to range accuracy. We develop a method that performs nonlinear filtering on the received signal energy to mitigate multiuser interference (MUI); and we test it over time-hopping and direct sequence impulse radio ultrawideband signals. Simulations conducted over IEEE 802.15.4a reside...
