With progress in radar systems, a number of methods have been developed for signal processing and detection in radars. A number of modern radar signal processing methods use time-frequency transforms, especially the wavelet transform (WT) which is a well-known linear transform. The interference canceling is one of the most important applications of the wavelet transform. In Ad-hoc detection met...

It is suggested that sublingual nitroglycerine can improve the ability of T1-201 for detection of viable myocardium. Methods and Results: In a randomized, double blind study, 50 patients who had fixed defects on stress-redistribution scan, were randomized into two groups. In group I, patients received 0.4-0.8 mg sublingual nitroglycerine, before T1-201 reinjection. In group II, reinjectio...

In the parallel signal processing, the multi-user detection precision of parallel interference cancellation (PIC) detector is always easily affected by the decision error diffusion. Based on the fast convergence and low complexity of blind adaptive Kalman algorithm, a new blind adaptive Kalman-PIC (KPIC) multi-user detection (MUD) algorithm is proposed for the direct sequence spread spectrum co...

In light of the ever-increasing demand for new spectral bands and the underutilization of those already allocated, the new concept of Cognitive Radio (CR) has emerged. Opportunistic users could exploit temporarily vacant bands after detecting the absence of activity of their owners. One of the most crucial tasks in the CR cycle is therefore spectrum sensing and detection which has to be precise...

Abslracf-In this paper, we consider the blind multiuser detection problem for asynchronous CDMA systems operating in a multipath environment. Using only the spreading code of the desired user, we first mitigate the effect of multiple access interference (MAI) while employing the constrained optimization. The constant modulus algorithm (CMA) is then applied to reliably recover the transmitted in...

Abslract--This paper addresses the problem of blind start-up scheme to the decision-directed MMSE algorithm for CDMA receivers. A ne\+' blind start-up scheme is proposed. I t is based on a new code-aided blind algorithm that adopts an approximate MSINR criterion. Furthermore, it is capable of utilizing the detectcd data symbols of the users that previously entered the net and have switched to t...

This paper presents an approach to blind texture detection in images based on adaptation of the 2DLookup algorithm by Genetic Programming. The task of blind texture detection is to separate textured regions of an image from non-textured (as e.g. homogeneous) ones, without any reference to a priori knowledge about image content. The 2D-Lookup algorithm, which generalizes the well-known co-occurr...

Although early blind (EB) individuals are thought to have a better musical sense than sighted subjects, no study has investigated the musical rhythm and beat processing abilities in EB individuals. Using an adaptive 'up and down' procedure, we measured the beat asynchrony detection threshold and the duration discrimination threshold, in the auditory and vibrotactile modalities in both EB and si...

An approach for detecting and tracking vehicles are proposed in these paper. Traffic safety applications using vehicle-to-vehicle communication is an emerging and promising area within the environment. By using a single rear-mounted fisheye camera and multiple detection algorithms to find the blind zone of the vehicle. It is driving safety supported system. Furthermore, the effects of fisheye d...
