Abstract
A pulse data coding method for wireless signal transmitting and receiving devices includes the steps of using a transmitter to transmit a signal of pulse data to be transmitted, transmitting at least one identification code pulse signal after a predetermined time interval from the transmission of the pulse data signal, and transmitting a check code pulse signal after another predetermined time interval from the transmission of the identification code pulse signal. The check code pulse signal is obtained by coding the pulse data signal and the identification code pulse signal according to a predetermined coding process. When a corresponding receiver receives the signal from the transmitter, it determines a correctness of the received signal according to the predetermined coding process, which may be an algorithm of addition, subtraction, multiplication, division, and/or a ratio operation.
