Patent attributes
Based on a received signal of a wireless communication system currently used for communication, a communication quality in a case of switching to another wireless communication system for communication is efficiently and precisely estimated. A communication quality estimating part (201) subjects both a known signal received, by use of a first wireless communication system, from a radio part (200) and a reference signal outputted from a reference signal storage part (203) to a conversion processing unique to a second wireless communication system for comparison, thereby artificially estimating the communication quality in a case of using a second wireless communication system for communication under the same wireless transmission path environment.
