<P>PROBLEM TO BE SOLVED: To provide a reception device high in possibility of reception success on a transmission-side radio terminal basis or on the basis of signals passing through transmission paths having channel characteristics close to one another with respect to a plurality of different transmission-side radio terminals, and preferentially using an equalizer of a stable equalization characteristic. <P>SOLUTION: A plurality of equalizers 106-1 to 106-n having equalization characteristics different from one another, demodulators 107-1 to 107-n of the next stages to the respective equalizers 106-1 to 106-n, decoders 108-1 to 108-n, and error determination units 109-1 to 109-n are arranged. A controller 110 selects one or more of the equalizers from among the plurality of equalizers 106-1 to 106-n by referring to information of use priority, and equalizes a reception signal. The controller 110 updates the information of the use priority by using at least one of detection frequency of a signal from which the determination result of the reception success has been obtained, detection timing and reception success frequency of the equalizers based on the determination outputs of the error determination units 109-1 to 109-n. <P>COPYRIGHT: (C)2011,JPO&INPIT |
