Automatic radio environment measurement system for QTT site

A Decision Support System for Parking Site Selection in Urban Environment, case study:Tehran city

Nowadays almost all big cities are confronting heavy traffic and suffering from lack of parking lots which leads in traffic jam. According to the significant role of vertical parking in reducing the traffic load and smoothing the traffic current; this study was carried out with the purpose of presenting a decision support system for vertical parking site selection for mechanical and constructiv...

Automatic compensation system for impedance measurement

This paper deals with the realization of the four-pair terminal definition of impedance standards. A simple, though reliable, system is described that allows an automatic compensation of the voltage at the low potential port of impedance standards to be obtained. Such a system employs a commercial data acquisition board and a signal generator with adjustable-phase capability, which acts as the ...

Downlink channel estimation for LTE OFDMA system under radio environment

The 3rd generation partnership project (3GPP) long term evolution (LTE) project is designed for high speed data rate, higher spectral efficiency, improved services, and lower latency as well as high-capacity voice support. LTE uses orthogonal frequency division multiplexing access (OFDMA) scheme for the downlink and single carrier frequency division multiple access (SCFDMA) in uplink. Main chal...

Radio data system for automatic tuning and other applications in FM radio receivers for use with pilot-tone system

A Semi-automatic Image-based Measurement System

Image-based measurement systems have been used in various surveying applications for several years. Unfortunately, most of such systems required artificial targets defining object points. To overcome this restriction the texture on the surface of the object can be used to find interesting points. However, well-trained “measurement experts” are required to operate such a measurement system. In o...
