<p><P>PROBLEM TO BE SOLVED: To provide a communication system using state information represented by shift time of a code system, which allows high speed transmission under noise environment by simple structure. <P>SOLUTION: A code type receiver 200 used opposite to a code type transmitter 1 which transmits input data by converting it into the shift time of a code pulse train is equipped at least with: a detection means 210 for receiving a transmission signal to output a detection signal; a synchronization means 220 for capturing or holding synchronization; a local signal detection means 240 for separating the code pulse train in which the data are converted into the shift time from the detection signal; a retention detection means 250 for removing noise superimposed to the separated code pulse train using a retention value of a correlation function of the code pulse train to detect the code pulse train and a data calculation means 260 for calculating data from the shift time of the detected code pulse train. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
