For the theme of graduation thesis, pick up the mobile communication related issues familiar to the students and reach a solution in consideration of the mobile radio networks from diversified viewpoints. At first, read a technical book in turn, and reconfirm the knowledge on mobile communications. For the theme of master’s thesis, study the system capacity increasing technologies and external degradation affects, and clear the availability of technologies and the impact of those affects to the system capability, to realize future broadband mobile communication systems.
