There is considered some methods of metrology testing of intelligent measurement systems. Also there is shown the necessity of simulation of components of measurement channel for investigation of the intelligent functions of the intelligent measurement systems in the accelerated time scale. Developed the metrology software test of temperature measurement channel using thermocouple. The results ...

An extensive measurement campaign has been carried out in the 4th floor of the Electronic Engineering Department of the University of Rome Tor Vergata. The measurement plan was described in the report numbered W03-02-0011-R03, available on the ULTRAWAVES private website. In this document we describe the first measurement campaign based on the use of the preliminary DVP purchased from Wisair. Su...

− This paper presents dynamic radio channel measurement using a fast wideband complex radio channel sounder and an antenna array. Examples of continuous channels of a moving mobile are presented. The array reception allows the investigation of channel dispersion in both angle and time. In addition, wideband measurement gives information of the coherence bandwidth of the 2D channel, essential fo...

When using the sharing spectrum with others communication system, the most important thing is considering about harmful interference from unlicensed to licensed systems. With TV-band also, the digital television (DTV) can tolerate the interference from other system with their threshold and sharing spectrum regulations can guarantee the interference between communications system was characterize...

A novel method for direct extraction of deep-submicron MOSFET effective channel length is proposed, which requires only a single measurement of the “critical-current at linear-threshold” (“Icrit @ Vt0”) based on the maximum-gm definition. With a simple calibration of the channel sheet resistance from the long-channel Icrit data, the effective channel length of any short-channel device on the sa...
