PURPOSE:To eliminate the demodulation error of data by comparing two correlation outputs on a reception side and assigning 0 or 1 of received data according to the comparison result. CONSTITUTION:In a data section, the correlation output Ra or Rb has a correlation peak. For example, when the correlation output Rb has the correlation peak, the total AbE of its preceding and following values is smaller than the total AaE of the correlation output Ra having no correlation peak, so the products of the peak values of the individual correlation outputs and totals, i.e., PbW.AaE and PaW.AbE are compared to generate demodulation data without generating any demodulation error. Consequently, even when the transmission characteristics of a transmission line, etc., are inferior and noise is easily generated, stable demodulation is enabled. |
