МІКРОХВИЛЬОВА ІНТЕГРОВАНА ТЕЛЕРАДІОІНФОРМАЦІЙНА СИСТЕМА МІТРІС-МЮІМИКРОВОЛНОВАЯ ИТЕГРИРОВАННАЯ АНТЕНА МИТРИС-МЮИ

摘要

A microwave integrated teleradio information system MITRIS comprises a subsystem for receive, forming and processing information with output connected to inputs of a central station including a microwave transmitter, a transmitting antenna that is connected with the microwave transmitter by means of RF line, programmed converter-former of IF group signal having N inputs and one output being united with input of a microwave transmitter, a user receive station. The microwave transmitter is presented as a spread spectrum microwave filtration unit for amplification and frequency conversion of signal of intermediate frequency (IF). The station comprises an antenna, a converter with low noise, and also a booster converters. To raise spectral efficiency of a communication line the central station is equipped with N combined modulators -/ with outputs being connected to N inputs of programmed converter-former of IF group signal. Every receive user station is equipped with a selective demodulator converter of frequency and a tuner of DVB-C standard.
