Abstract

The capacity of satellite DMB (digital multimedia broadcasting) system could be limited mainly by the mutual interference of neighbor satellite DMB system. So, to achieve the expected performance of satellite DMB system, ACI (adjacent channel interference) from other satellite DMB Systems should be considered carefully. Satellite DMB system usually deploys gap-filler for effective transmission in terrestrial environment, and the gap-filler may use direct amplification or frequency conversion to satisfy the specific requirements. Therefore, amplified signal causes several adverse effects on interference between system A (Eureka 147 DAB) and E (ISDB: integrated services digital broadcasting ). In this paper, by considering the outcome of system-level simulation considering the results of link-level simulation, we analyze the interferences between system A and E under practical situation based on the exact parameters of ITU-R BO. 1130-4. We also propose the appropriate size of guard band & cell radius to optimize system capacity by adapting the spectrum mask given in the spec and utilizing the interference analysis between system A and E
