We have been proposing a direct spectrum division transmission (DSDT) technique that can divide a single carrier signal into multiple sub-spectra and assign them to dispersed frequency resources of a satellite transponder to improve spectrum utilizing efficiency. This letter overviews the concept of DSDT and shows the results of feasibility verification on DSDT via satellite experiments. 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. The BER performances of signals divided by the DSDT technique were almost the same as that of a single-carrier. We confirmed that DSDT was practical.
