GPS signals are susceptible to interference levels above the inherent processing gain of the receiver. In this paper an innovative approach to cancel narrowband interference is presented. An Adaptive Temporal Filter (ATF) based on a Transversal form that pre-filters the interference before correlation is studied. The adaptive algorithm used to adjust the filter coefficients is the RLS algorithm...

When using electrical-balance duplexers (EBDs) to provide RF self-interference cancellation for in-band full-duplex, in-band distortion produced by nonlinear CMOS switches in the duplexer cause distortion that limits the headroom for additional self-interference cancellation in subsequent cancellation schemes in the transceiver. A prototype EBD is fabricated in 0.18μm SOI CMOS to investigate th...

We look at multiple-track detection for magnetic recording systems that use array heads to write and read over multiple tracks simultaneously. The recording channel is modeled as having intersymbol interference (ISI) in the axial direction, and intertrack interference (ITI) in the radial direction. Optimum multihead and single-head detectors are derived and analyzed in terms of error-probabilit...

High-Quality Detection in Heavy-Traffic Avionic Communication System Using Interference Cancellation Techniques by Minh Nguyen This dissertation focuses on quantifying the effects of multi-user co-channel interference for an avionic communication system operating in a heavy-traffic aeronautical mobile environment and proposes advanced interference cancellation techniques to mitigate the interfe...

The vulnerability of civil GPS receiver to interference may be intentional or unintentional. Among all types of interference, replay attack intended as the most dangerous intentional one. The signal structure of replay attack is almost the same with the satellite signal. The interference effects can be reduce with the design of an appropriate filter in the receiver. This paper presents two meth...

In this paper, we focus on the interference management in the cognitive radio (CR) network comprised of multiple primary users (PUs) and multiple secondary users (SUs). Firstly, two interference alignment (IA) schemes are proposed to mitigate the interference among PUs. The first one is an interference rank minimization (IRM) scheme, which aims to minimize the rank of the joint interference mat...

This paper uses CSP to introduce a characterisation of non interference in terms of the deductions that may be made about high level processes by low level tests May testing yields classic noninference and has a concise formulation in CSP It is preserved by a wider range of composition oper ators than are normally considered in the context of non interference It turns out that the extensive lis...

the modeling investigation in this paper discusses the system level effects of a toxicant on a three species food chain system. in the models, we have assumed that the presence of top predator reduces the predatory ability of the intermediate predator. the stability analysis of the models is carried out and the sufficient conditions for the existence and extinction of the populations under the ...

GNSS receivers have been shown to be most vulnerable to CW interference. It affects the acquisition process of the signal and can also pass through the tracking loop filters to affect the received satellite signal quality. Carrier to noise density ratio (C/No) is an indicator of received signal quality to the receiver. Lower C/No means lower quality of the received signal. Galileo satellites wi...
