Diverzitní kombinování signálů ze všesměrových satelitních pozemních stanic

Abstract

A typical ground station consists of a high directional antenna placed on the antenna rota-tor. The solution has disadvantages like the high cost of antenna or low-reliability of an-tenna rotator, and the capability to track only one satellite at a time. It can be replaced by many omnidirectional ground stations with diversity combining to substitute the missing gain of the omnidirectional antenna. This bachelor thesis considers developing an algo-rithm for non-coherent signal combining from several omnidirectional ground stations due to the lack of antenna gain of these omnidirectional ground stations.
