| Research Abstract |
We propose 16-and 32-ary modulation schemes and dual-polarized scheme as methods to increase satellite broadcasting capacity significantly. Link performance is simulated using MATLAB/SIMULINK software assuming modulated signal propagates in rain-filled medium. We noticed the above methods are available if attenuation countermeasure technology works effectively. As for attenuation countermeasure technology, we evaluated quantitatively diversity methods using rainfall rate and attenuation data measured in Japan and Asian countries.
