| Abstract(in English) | A new satellite onboard processing system using DSP and FFT technologies are proposed. In order to increase system capacity, use of hundreds to thousands multiple beams is assumed. The system provide flexible transparent bandwidth to mobile users or small transportable terminal users. The multiple beam received signal at satellite are sampled and changed to digital form, then, transformed to frequency region by FFT. Required number of FFT is determined by the smallest bandwidth required. Result of FFT, which shows frequency domain samples, are stored in the up link memory in every FFT operation. Selection of the up link beam and selection of the up link channel are performed by selection of the address of the up link memory which was refreshed after every FFT operation. By these procedure, flexible bandwidth allocation and bandwidth routing are made possible. The reading of up link memory are performed for each down link channel in every down link beam. Requirement for complex receiving system configuration, flexible channeling, FFT procedure and handling of continuous signal are also presented. |
