WiMAX carries the promise of ubiquitous broadband wireless access enabling real-time and multimedia applications. WiMAX networks are being deployed worldwide to bridge the digital divide and to help countries with no previous infrastructure provide broadband access to users. This paper studies path loss and propagation models using deployed WiMAX network(More)
—Performance of a diffuse optical link may potentially be degraded by temporal dispersions resulting from surface reflections. In order to devise techniques to alleviate the adverse effect of dispersion, an accurate channel model is needed. Obtaining the impulse response (IR) for a given receiver location requires not only consideration of direct path, but(More)
To address the rising costs of health care accessibility, we propose a solution that takes advantage of the ubiquity of broadband wireless coverage and wide spread usage of smart phones around the world. The solution presents a web based health monitoring system that takes advantage of mobile capability, cloud storage and high speed access. The solution(More)
—Angle diversity is an effective technique to compensate for multipath temporal dispersion in a wireless infrared environment. Diversity is accomplished by using a multibranch receiver capable of resolving multipath. The goal of this paper is to illustrate the effect that the increasing diversity order of a receiver has on the performance of a link in a(More)
Optical (infrared) wireless communications links offer an attractive solution for indoor applications. To enable terminal mobility and reduce temporal dispersion, we use a configuration known as Multi-Spot-Diffusing (MSD), which is a Multi-Input, Multi-Output (MIMO) architecture. In this configuration, a transmitter generates multiple narrow beams that get(More)
The rapid deployment of WiMAX technology around the world enables research based on actual field measurements. This work reports on one important aspect of network deployment, power analysis. This work considers a mobile WiMAX network operating at 3.5 GHz deployed in Amman, Jordan and reports on measured signal power, transmitted signal power, carrier to(More)
Traditionally, diffused infrared configuration has been studied with the assumption that the illuminated region is placed at room ceiling. This is done to ensure minimum path loss to a maximum number of receiver locations. In many practical situations, this arrangement might be difficult to implement, either due to the ceiling structure or the difficulty in(More)
Engineering education is constantly challenged to bridge the gap between classroom and real world problems. In this paper, we report on the experience at PSUT of complementing the teaching of digital signal processing through project based learning. A low cost digital stethoscope is utilized by students to record heartbeat sounds and apply DSP concepts to(More)
