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...

In this contribution a new concept for the rapid development of real-time prototypes for digital signal processing algorithms on a General Purpose Personal Computer (GP-PC) based on the Windows operating system (Windows OS) is presented. In this approach, hardware and algorithm related programming issues are separated in order to liberate the designer from problems which are not related to the ...

A mixed-signal architecture for estimating the 3-D direction cosines of a broadband traveling wave impinging on an array of four sensors is presented. The architecture implements gradient flow, which converts the problem of resolving time delays between sensor observations into the problem of estimating relative amplitudes of spatial and temporal derivatives over the array. Direction cosines of...

In this study we explore the performance gain that can be achieved at the network level by employing successive interference cancelation (SIC) instead of treating interference as noise for random access wireless mesh networks with multipacket reception capabilities. More precisely we explore both the throughput and the delay of a distributed flow allocation scheme aimed at maximizing average ag...

Quantum computation has demonstrated advantages over classical for special hard problems, where a set of universal quantum gates is essential. Geometric phases, which have built-in resilience to local noise, been used construct with excellent performance. However, this advantage smeared in previous schemes. Here, we propose state-independent nonadiabatic geometric quantum-gate scheme that able ...

For several decades Proportional-Integral-Derivative control (PID) has been successfully used for a wide variety of industrial processes and remains the most used method. Recent work concerning the tuning of PID control coefficients has been proven to provide both robust and near-optimal performance using a Frequency Loop Shaping (FLS) procedure. The FLS tuning method minimizes the difference b...

BACKGROUND Impulsivity is a core feature of borderline personality disorder (BPD) and attention deficit hyperactivity disorder (ADHD). In BPD, impulsive behavior primarily occurs under acute stress; impulse control deficits under non-stress conditions may be partly related to co-morbid ADHD. We aimed to investigate whether acute experimental stress has an impact on self-reported impulsivity, re...

Response inhibition is disturbed in several disorders sharing impulse control deficits as a core symptom. Since response inhibition is a cognitively and neurally multifaceted function which has been shown to rely on differing neural subprocesses and neurotransmitter systems, further differentiation to define neurophysiological endophenotypes is essential. Response inhibition may involve at leas...
