Recently, the marginalized particle filter (MPF) has been applied to blind symbol detection problems over selective fading channels. The MPF can ease the computational burden of the standard particle filter (PF) while offering better estimates compared with the standard PF. In this paper, we investigate the application of the blind MPF detector to more realistic situations where the systems suf...

In this paper, an adaptive semi-blind multiuser detection (MUD) algorithm based on improved projecting approximation subspace tracking with deflation (PASTd) subspace tracking is proposed for multicarrier code division multiple access (MC-CDMA) uplink where the base station receiver has the knowledge of the spreading sequences of all the users within the cell, but not that of the users from oth...

In this paper, we propose a robust blind multiuser detector for code-division multiple access (CDMA) systems against signature waveform mismatch (SWM) derived from the influences of time asynchronization or channel distortion. This blind detection method with SWM problem is formulated as blind source separation (BSS) model subject to the second-order cone (SOC) constraint. The resulting blind s...

PURPOSE To compare blind-side detection performance of drivers with homonymous hemianopia (HH) for stationary and approaching pedestrians, initially appearing at small (4°) or large (14°) eccentricities in a driving simulator. While the stationary pedestrians did not represent an imminent threat, as their eccentricity increased rapidly as the vehicle advanced, the approaching pedestrians mainta...

statement of problem: blindness as a disability seems to produce difficulties to reach an ideal heath status of the teeth. moreover ordinary educational health programmes for this group of population, especially children, are not successful. purpose: investigate the dental health status of these children and to see if they are really different with the normal population. materials and methods: ...

This paper describes a vision-based vehicle detection system for a blind spot warning function. This detection system has been designed to provide ample performance as a driving safety support system, while streamlining the image processing algorithm so that it can be processed using the computational power of an existing ECU. The procedure used by the system to detect a vehicle in a blind spot...

Purpose Drivers with homonymous hemianopia (HH) were previously found to have impaired detection of blind-side hazards, yet in many jurisdictions they may obtain a license. We evaluated whether oblique 57Δ peripheral prisms (p-prisms) and perceptual-motor training improved blind-side detection rates. Methods Patients with HH (n = 11) wore p-prisms for 2 weeks and then received perceptual-moto...

Breast cancer is the most common cancer in women worldwide; and its incidence is increasing in many countries. Breast SelfExamination (BSE) is a simple and easy way to detect any changes in the breast and help in early detection of breast cancer, which is highly recommended in young age started from age of 20 years. The aim of the study is to determine breast cancer knowledge, and BSE practices...

This paper provides an investigation into the performance of a multi-stages constant-modulus filter/ signal canceller (CMA/SC) for blind detection of direct sequence/code code division multiple-access (DS/CDMA) signals over additive white Gaussian noise (AWGN) channels. A simple stochastic gradient algorithm for implementing the scheme is presented and the convergence properties of the algorith...
