| Outline of Final Research Achievements |
Continuous phase modulation (CPM) has constant envelope and good spectral properties. Therefore, it is suitable for aeronautical communication systems that require high reliability in long distance communication.
On the other hand, recent broadband mobile communication systems use space time block codes (STBCs) to obtain channel gain using multiple antennas. STBC-CPM is a combination of STBC and CPM, having the advantages of both techniques. We proposed STBC-CPM system which has spectral efficiency and power efficiency at the same time. The spectral efficiency of STBC-CPM was compared, then we found that non-orthogonal STBC can be used to improve the spectral efficiency of STBC-CPM sytem.
