    Abstract: PROBLEM TO BE SOLVED: To improve both transmission capacity and communication reliability by selecting an optimal communication method and transmission mode. SOLUTION: There are provided a plurality of systems of reconfigurable radio processing unit 102 whose function and performance can be modified. A control unit 104 collects quality information on the communication link in communication methods received at respective radio processing systems 102a, 102b. According to this, the control unit 104 selects an optimal communication method and transmission mode from a plurality of communication methods and transmission modes (for example, diversity transmission between a plurality of systems, diversity transmission by a single communication method, and MIMO channel multiplex transmission). By modifying configurations of the reconfigurable radio processing unit 102 according to the selected communication method and transmission mode, it is possible to communicate at a desired transmission mode. Thus, it is possible to perform an optimal transmission to the communication link according to the quality condition. COPYRIGHT: (C)2009,JPO&INPIT
