Recent literature provides initial evidence that sound can be used for cognitive development purposes in blind children. In this paper we present the design, development, and usability testing of AudioBattleShip, a sound-based interactive environment for blind children. AudioBattleShip is an interactive version of the board Battleship game, providing different interfaces for both sighted and bl...

Current research on “Usable Security” is still in its infancy and usable security solutions are often designed without paying attention to human disabilities. This paper aims to help fill this void in the realm of blind computer users. More specifically, we discuss research challenges we are faced with and the directions we can take towards developing authentication technologies suitable for th...

Blind deconvolution is an ubiquitous non-linear inverse problem in applications like wireless communications and image processing. This problem is generally ill-posed, and there have been efforts to use sparse models for regularizing blind deconvolution to promote signal identifiability. Part I of this two-part paper characterizes the ambiguity space of blind deconvolution and shows unidentifia...

Multi-antenna receivers are a key technology for modern communication systems. Signal attenuation in the very low frequency (VLF) channel is serious problem. In addition to high signal attenuation, resulting noise on VLF non-Gaussian. Hence, analyze and address issue of normal operation multi-antenna receiver channel, we must study detection problem multi-dimensional non-Gaussian fading channel...

This paper deals with the design of blind mobile station (MS) receiver for time-hopping (TH) ultrawide-band (UWB) impulse radio (IR) system employing antipodal pulse amplitude modulation (PAM). In the presence of multipath fading channel, batchmode minimum output energy (MOE) receiver, as well as a blind channel estimator, is first developed. To reduce the computational complexity, we propose t...
