Abstract
We have been studying a direct spectrum division transmission (DSDT) technique that can divide a single carrier signal into multiple subspectra and assign them to dispersed frequency resources of the satellite transponder to improve the spectrum efficiency of the whole system. In a past study, we carried out fundamental satellite experiments on DSDT over a single transponder. This time, we conduct satellite experiments on DSDT over multiple transponders by using the latest DVB-S2X format signal. We expect using DSDT over multiple transponders will provide a new type of satellite communication service by raking unused frequency resources dispersed through multiple transponders.
