Spectrum Monitoring System Simulation

Abstract

With rapid development of communication industry, the kinds of communication service vary, according to the increasing use of radio waves, the intelligent and effective radio monitoring system needs to be developed, which is replaced for previous radio monitoring system. Next-Generation Intelligent Radio Monitoring System based on ITU-R, Rule of wireless facilities, and Radio Waves Act is used, and which can accurately and effectively function as effective radio monitoring system through spectrum analysis of channel power, frequency deviation, offset, and an occupied frequency bandwidth, about the analog and digital signal in On-Air of V/UHF bandwidth. In this paper, we proposes method of radio measurement and radio management through the radio quality measurement, unwanted electromagnetic signals(spurious, harmonic) measurement, high-speed spectrum measurement, frequency usage efficiency investigation, illegal radio exploration. The objective of this project was to design a system to allow monitoring for electro morganatic waves or radio waves remotely via computer without the presence of man and to reduce the time factor. There are two key components to the project design, 1-Remote unit This unit consists of computer is present in the remote place. 2-Local unit This contains of computer and a Local Control Section, Local Control Section consists of a DTMF Receiver (DTMF decoder), BASIC Stamp 2-IC, ULN2003 Darlington Driver and the radio waves The remote unit (computer) was detected successfully the illegal random waves.
