Abstract (in Japanese) (See Japanese page) 
(in English) A great variety of wireless systems are currently being used to provide diverse and sophisticated information and communication services. New wireless systems are being standardized for later implementation. We have proposed a new flexible wireless system (FWS) supporting for a wide variety of wireless systems. Since FWS receives multiple signals simultaneously, the widening of received signal power and the confliction of received signal become a big problem. To solve these problems, we propose a new multi-band receiver and multi-band auto gain control (AGC) method. Moreover we propose a signal separation method using a desired signal features extracted from the received radio wave. This system processes all received radio wave with software on the network. We develop a prototype of the flexible wireless system to confirm its effectiveness. We show the effectiveness of these proposed technologies for multi-band multi-signal reception by using a computer simulation and with the prototype.
