Summary:PROBLEM TO BE SOLVED: To receive a plurality of channels without having to increase hard ware. SOLUTION: A demodulating part 720 is composed of a digital signal processor or the like, respectively performs filter arithmetic processing of the digital data of two channels, which are subjected to baseband conversion by orthogonal detectors 713 and 715 and detects channel selection and a symbol identification point. Then, the demodulating part 720 carries out demodulation processing, extracts data in the symbol identification point and demodulates data corresponding to two channels.
