Abstract

The article is discusses the monitoring and diagnostics system with the simulator of the multipath channel for the mobile digital troposcatter-radiorelay station. The specificity of such a digital combined telecommunication microwave system: manifestation of a single system control and diagnostics for both components of the station; congestion to the multipath-beam simulator of a fading channel with the storage at the warehouse control system and diagnostics; single frequency former for both components of the station. At the digital combined telecommunication microwave station there is space diversity reception. Parameter monitoring in possession and diagnostic of the control panel of a mobile digital telecommunication microwave system. In the article, the main functions of the control and diagnostics of such a digital combined telecomunication microwave system, the main task of awakening the multipath simulator with wired ones. In the article shows the modeling of the multipath channels is equipped with system functions. The mathematical apparatus of statistical analysis for the system functions must be accelerated by a large number of specific practical problems, the frequency-selective fading and inerference. In the article there are system functions of multipath channels and channels that can be retransmitted with information on the several frequencies by elliptic functions and elliptic integrals. This science-based result is widespread on channels that can be retransmitted with information on the several frequencies. System functions have the logarithmic singular points. It is shown that the system functions can be represented through a theta-functions and elliptic integrals. Elliptic functions Jacobi can be twisted through a theta-function.

Keywords: troposcatter communication, multipath channel, troposcatter-radiorelay station, interference, multipath-beam simulator, elliptic function, elliptic integral, theta-function.
