We show the development of a wideband delay guided by the closed-form, analytic solution of a solvable chaotic oscillator. This delay serves as a crucial component in the design of a matched filter receiver that optimally detects chaotic waveforms in

The increased throughput performance of physical-layer network coding (PNC) has led to rigorous research in this field for two-way relay systems or multi-way systems. For coherent detection of information received by the relay node and decoding the c

The main goal of Vehicular Ad Hoc Networks (VANETs) is to improve driving safety. However, VANETs may not guarantee timely detection of dangerous road conditions or maintain communication connectivity when the network density is low, which may pose a

Two wireless nodes outside each others radio range can communicate via a node in between, known as a relay node. A relay node may be a simple repeater or a fully functional entity depending upon the deployment scenario. In a two-way relay communicati

The engineering community is confident in its assessment of how an angle tracker will perform in a multitarget environment as the target-to-tracker range decreases, causing targets to leave the tracker antenna beam. When one target signal dominates d

Some of the biggest investments surrounding Global Navigation Satellite System (GNSS) receivers are the development and integration of adaptive nulling technology. Researchers, developers, and integrators need to understand the effects these nulling

It is well known that civilian Global Positioning System (GPS) receivers are vulnerable to interference. Robust interference reduction can be accomplished through a combination of temporal and spatial filtering using antenna arrays; however, current

Evolving global navigation satellite system (GNSS) threats are becoming a concern for all unmanned aerial systems (UAS) dependent upon GNSS aided navigation. More and more UAS platforms are considering integration of GNSS anti-jam (AJ) electronics an

In this paper we introduce frequency hopping spread spectrum (FHSS) into Diagonal Bell Laboratories Layered Space-Time (D-BLAST) Multiple Input Multiple Output (MIMO) architecture. We evaluate the performance of the system containing a single interfe
