PURPOSE:To improve the reliability of transmission by sending a data pulse signal while keeping the pulse width per bit longer than the width of burst noise so as to correct a bit error over plural bits. CONSTITUTION:A transmission data added with an error check data from a transmission device 1 is sent in a form of a radio signal and a reception section 2a of a receiver 2 receives the radio signal and a signal processing section 2b applies an error check of the transmission data based on an error check data. In this case, a data signal (d) expanding the pulse width per one bit than the width of a burst noise is sent from the transmitter 1. Then even when the burst noise is generated, the bit error in the reception signal received by the receiver 2 due to the burst noise is only 1 bit as shown in figure (e) and the error is not given over plural bits. |
