Research on Cooperative Diversity in Mobile Satellite Communication System

In order to improve the system performance, the cooperative diversity technology was been adopted to obtain the diversity gains in mobile satellite communication system. First, the feasibility of cooperative diversity in mobile satellite communication system was analyzed. Second, we present a satellite mobile cooperative communication system model and derive two generalized error probability expressions with CRC (Cyclical Redundancy Check) or not. We also derive and simulate SER of the proposed system over different satellite mobile channels. Last, symbol-errorrate (SER) performance analysis is provided for a decode-and-forward cooperative scheme in mobile satellite communication system. The results show that the analytical results are in great accordance with the ones obtained by simulation. Also, it was shown that, whether or not adopt CRC depends on the channel link quality between the source node and the relay node.

W celu poprawy parametrów systemu komunikacyjnego zaadaptowano technologię kooperacyjne różnorodności. Przeanalizowano wykonalność kooperacyjnej różnorodności w systemach mobilnych komunikacji satelitarnej. Następnie określono błędy prawdopodobieństwa w systemach z CRC I bez CRC. Analizowano także parametr SER.
