Recent Developments in Uhf and Microwave Terrestrial Television in the Uk

Exploiting digital terrestrial television for the support of tele- learning applications

This paper presents the potentialities of the new digital television in UHF (Terrestrial Digital Video Broadcasting– DVB-T) in supporting novel tele-learning applications, such as the “virtual classroom”, where the lecturer and the students are virtually present in the same classroom from their own premises. Based on the ATHENA FP6-507312 concept for the transition from analogue to digital terr...

Low Pass Filter Design Comparison Using Agilent Genesys

Wireless communication is becoming more and more popular. In this paper, a maximally flat low-pass filter and a equal-ripple low-pass filter have been designed for Ultra High Frequency (UHF) band ie I.T.U. band 9 (Frequency 300Mhz – 3000Mhz; Wavelength 1m – 100mm).Application of UHF band includes television, microwave ovens, mobile phones, wireless LAN, Bluetooth, etc. The filters are designed ...

A path-specific propagation prediction method for point-to-area terrestrial services in the VHF and UHF bands

Proximity Identification and Tracking for Mining Automation

A priority issue within coal mines is ensuring the safety of underground personnel. It is vitally important to have upto-date information about: which districts personnel are working; if there is adequate provision of safety equipment and facilities, and whether the mine enviroment is hazardous. This paper canvasses recent developments in proximity identification and tracking techologies for mi...

A 3D Polar Processing Algorithm for Scale Model UHF ISAR Imaging

In recent years, UHF synthetic aperture radar has become a growing area of interest among the radar community. Due to their relatively long wavelengths, UHF systems provide advantages that may not be attainable by microwave and millimeter-wave radar systems. These advantages include excellent target detection statistics in high clutter environments, wide-area surveillance, and long stand-off ra...
