Design and Implementation of an Indoor Ultrasonic Communication System

Ballal, Tarig ; Saad, Mohamed M. ; Bleakley, Chris (The Institution of Engineering and Technology, 2011-06-22)

In this paper, an indoor communication system using ultrasonic signals is described. The system uses differential binary phase-shift keying (DBPSK) for transmitting binary data as a part of an indoor positioning system. A ...
High accuracy Location Estimation of a Mobile Tag using One-way UWB Signalling

Saad, Mohamed M. (IEEE, 2012-10-03)

This paper presents a novel algorithm for determining the 3D location of a Mobile Tag (MT) using wireless Base Stations (BSs) and Ultra Wide Band (UWB) one-way signaling. The algorithm is designed for low power, rapid ...
High Accuracy Reference-free Ultrasonic Location Estimation

Saad, Mohamed M. (IEEE, 2012-06)

This paper presents a novel reference-free ultrasonic indoor location system. Unlike most previous proposals, the mobile device (MD) determines its own position based only on ultrasonic signals received at a compact sensor ...
Robust High Accuracy Ultrasonic Range Measurement System

Saad, Mohamed M. ; Bleakley, Chris ; Dobson, Simon (IEEE, 2011-10)

This paper presents a novel method for ultrasonic range estimation. The method uses a wideband frequency-hop spread spectrum ultrasonic signal to increase robustness to noise and reverberation. The method applies ...
