This work considers the performance of none-light-of-sight (NLOS) target localization method using a distributed receiver array. The multipath propagation is modeled with single bounce reflection from unknown random scatters. A Simultaneous Target and Multipath Positioning (STAMP) method is proposed for jointly estimating the target and scatter positions given Time-of-Arrival (TOA) observations. The...
The paper discusses the cooperation method among multiple agents in 3D space based on intention recognition. It is assumed that an observer observes multiple moving objects that are its company and the enemy. The purpose of our work is to help the observer to make cooperation decision efficiently. Due to the distortions the perspective brings, cooperating in 3D space is difficult. To contact agents...
This work studies the performance of a data-driven reduced rank scheme for rapid timing acquisition in multiple access communications. Our results show that when only a limited amount of preamble bits are available, instead of the true second-order statistics (SOS), the reduced rank scheme provides reliable timing information. Exploiting the structure of the multiple access interference, the data...
In this paper, we focus on the security issue of a chaotic digital communication scheme called chaotic-pulse- position modulation. We design a third party intrusion scheme to test to see if CPPM is as secure as is claimed. Experiments are conducted with various chaotic maps, where CPPM is used to modulate the message at the transmitter and a Kalman filter fed with a polynomial approximation is used...
