An impulse radio ultra wideband (IR-UWB) pulse generator works between 5.5-10.5 GHz for narrowband interference mitigation is proposed. With an average power of -85 dBm/MHz from 0-5 GHz, high interference avoidance has been achieved for a wide range of narrowband systems including Global Positioning System (GPS), Worldwide Interoperability for Microwave(More)
Dust storm effect on microwave signal attenuation has attracted many researchers recently. Many prediction models have been developed in order to predict microwave signal attenuation during the dust storm. Most of the dust storm prediction models have ignored the variation of the particle size inside the dust storms. Therefore, their predicted results(More)
A novel design of 4-Gbps and 6-Gbps Impulse Radio Ultra Wideband (IR-UWB) pulse generator for short range wireless communication is presented. The simple structure of the proposed pulse generator helps to overcome the limitations of generating the two high speeds, the pulse generator based on two synchronized sources of 2 GHz only. The pulse generation(More)
Developing and less developing countries (LDCs) are identified in risk of stillbirth due to insufficient emergency medical take-care supports. The regular check-up of the fetal electrocardiography (FECG) could be an earliest prevention of this occurrence. This paper presents a research work aim to implement a simple, customize and portable emergency medical(More)
The advancement of the quantum computing is challenging the foundation of the cryptography by its almost unlimited computation power to predict the secure key that is thought to be absolutely secure based on the currently used algorithms such as the RSA and the Diffie-Hellman and others. The field of quantum cryptography on the other hand is providing the(More)
Monitoring a large number of interacting sensors, actuators and controllers in sensitive locations simultaneously, requires efficient and fast network. Sophisticated computer controlled systems in modern aircrafts have become a necessity. Wired connectivity can be both awkward and hazardous. In this paper we propose wireless connectivity based on(More)
Availability is one of the main factors to measure the QoS of any telecommunication networks. An accurate availability prediction for Free Space Optical link of carrier class grade is needed. In tropical areas, rain is the most dominant factor affecting the FSO link availability. In this paper, the effect of rain attenuation on the availability of FSO links(More)
A novel design is proposed for a 1-Gbps Impulse Radio Ultra Wideband (IR-UWB) pulse generator. The generated pulse is not just suitable for solving the problem of UWB interference with Wireless Local Area Network (WLAN) 802.11a and Worldwide Interoperability for Microwave Access (WiMAX) systems, but it has no interference on any narrowband system works(More)
