| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Communications system with which the communication satellite into which large diameter multi-beam antenna is loaded and the mobile terminals are connected is under developed. Consideration of the frequency use efficiency of digital channelizer is advanced for this system. This system has capability to give a reaction flexiblly to a traffic volume increase at a large scale disaster occurs by loading digital channelizer into the satellite. Channelizing is performed by the sub-band unit which is packed several channels by channelizer. But because optimal value changes by a parameter variously, the number of channels packed by a sub-band together is considered by parameter study. When fixed number double of the sub-band width was mainly the value near the feeder link width by the former study, which is showed that the frequency rate of utilization becomes good. But it was the condition this was all satellite beams, and that call amounts are fixed. Call amounts are absolute little in the sea area and non-uniform traffic which cause of large scale disaster in the disaster area were not considering the condition. So, study of optimal sub-band under the traffic condition which is non-uniform traffic in large scale disaster is reported. |
