PROBLEM TO BE SOLVED: To provide a radio communication system, a transmitter and receiver, and a radio communication system for performing radio communication with high quality by simple circuit configurations by using the stationary property of radio propagation characteristics in a case body. SOLUTION: A case body is provided with a transmitter 60a and a receiver 70a. A class classifying part 77 performs class classification, and sets a class code CC based on a signal RD obtained by receiving a radio signal. A coefficient signal KG corresponding to the class code CC is supplied from a storage part 78 to a waveform working processing part 75. The waveform working processing part 75 multiplies a signal RG whose waveform deformation is generated due to the influence of a multi-path or the like by the coefficient signal KG for generating a signal RGC whose waveform deformation has been corrected. A decision part 76 performs the logical decision of the signal RGC, and generates the signal RD showing the decision result. Even when any signal waveform deformation is generated due to the multi-path or the like, the waveform deformation is corrected, and logical decision is operated so that radio communication can be achieved with high quality.
