UHF Measurment

UHF fading in factories

There has been recent interest in characterizing UHF propagation within buildings and houses. Factory radio channels, however , have not been discussed previously in the literature. This paper details the results of narrow-hand propagation measurements performed at five factories. The extensive empirical data indicate that path loss is dependent upon local surroundings and is log-normally distr...

UHF RFID Reader Antenna

This chapter addresses the various design issues, requirements, and specifications in designing reader antennas for UHF RFID applications. In a typical UHF system, the RFID reader antennas are geography specific; that is, there are different antennas for different geography, namely North America, Europe, et cetera. The discussion on the design challenges and performance expectations lead to a n...

Computationally Efficient Non-intrusive Algorithm for Speech Transmission Quality Measurment

A new, wavelet-based, non-intrusive method for speech transmission quality measurements is described in the abstract. It models human perception of quality of transmitted speech signal. The deployed Discrete Wavelet Transform, in comparison with Fourier Transform, enables to reduce the computational power. In comparison with standardized methods (based on ITU-T P.563 algorithms), the described ...

Intelligent Traffic Light Control System Based Image Intensity Measurment

Vehicles growth leads to a big problem over the world including in crowded cities. The Intelligent traffic control algorithm is implemented to introduce many parameters, such as the crowded roads, the emergency vehicles and the intersection of roads. Intelligent cameras are connected for capturing real-time traffic flow images of each direction. The control system can automatically adjust the t...
