Abstract

The main objective of this paper is to find and identify the fading fluctuations in telemetry signals caused by no homogeneities of the communication channel. The employed methodology follows the next steps: remove the envelope of the signal amplitude; identifying the Gaussian component; identifying the non-Gaussian component and obtaining the statistical characteristics from Gaussian and non-Gaussian components. Then, the results are statistically treated in order to obtain a diffusion K parameter of Rician fading which are associated with fading in atmosphere and ionosphere layers. In this way the communications channel among satellite and ground station is characterized and a BER parameter can be obtained. The methodology is applied to telemetry signals of the Moscow State University microsatellite better known as "Universitetsky-Tatiana" and the results are discussed.

Оценка статистических характеристик замираний сигнала в системах спутниковой радиосвязи

Основной целью статьи является обнаружение замираний сигнала, обусловленных неоднародностями в канале телекомуникаций. Применяемая методология отвечает следующим этапам: удаление огибающей сигнала; обнаружение гауссовских и негауссовских компонент и получение их статистических характеристик. Таким образом можно охарактеризовать канал коммуникаций и получить параметр вероятности ошибки (BER). Методология применяется к телеметрическим сигналам микроспутника Московского государственного университета «Университетский-Татьяна».
