Next, a template waveform creator creates (22) a corresponding template waveform on the basis of information about waveform distortion obtained by this measurement. The receiver applies (23) this template waveform to decoding information portion of the packet to reproduce (24) the transmitted information (24). In addition, the scope also includes a method in which the propagation path state discriminating section is provided on the top of the header to perform decoding other than the propagation path state discriminating section of the header by using the template waveform. Also, the receiver creates template waveforms for a plurality of receiving signal waveforms, and makes an average value of the outputs into a final template waveform.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
