| Abstract(in English) | This paper proposes a channel allocation algorithm for demand assigned multiple access (DAMA) based satellite communication systems to effectively utilize various widths of unused frequency band in a satellite transponder. Our algorithm is based on the spectrum division transmission technique that divides a single carrier spectrum into a number of subspectra whose bandwidth and frequency are freely set depending on the transponder status. To decrease the number of spectrum divisions (=transition band) and widen the unused frequency band in the satellite transponder, we newly developed a best first fit (Best FF) method for our algorithm which well satisfies the spectrum division requirements. Simulation results showed that our algorithm enhances system capacity by as much as 1.3 times compared to other algorithms. |
