PURPOSE:To always decide a reception data correctly by adding n-bit data weighted at every bit in response to a reception electric field strength at data reception corresponding to bits and deciding the logical value of each bit for a transmission data based on whether the addition of each bit is larger or smaller than the setting value. CONSTITUTION:A transmission side sends n-bit data for plural number of times. A control section 15 receives an i-th n-bit data from a demodulation circuit 16 upon the data reception and a reception electric field strength at that time is fetched from an A/D converter 18. Then the weight in response to the reception electric field strength at data reception is obtained and the weight is multiplied at every bit with a numeral in response to the logical value of bits forming the reception data and each n-bit data weighted at every bit is added corresponding to bits and the logical value of each bit of the transmission data based on whether the sum of bits is larger or smaller than the setting value. Thus, the reception data is correctly decided independently of the reception electric field strength at data reception. |
