1. A wireless data transmitting and receiving system comprising:

  • a random number generator which generates a random number sequence;

    a random-interval pulse sequence generator which generates a random-interval pulse sequence of data, which is to be transmitted, using the random number sequence generated by the random number generator;

    a template pulse sequence generator which generates a reference template pulse sequence used to detect a start point of the random-interval pulse sequence and generates pulse sequences for a signal 0 and a signal 1 by changing widths of pulses;

    a random number sequence detector which receives the random-interval pulse sequence and detects information regarding a start point of a random number sequence, which is used to make the received random-interval pulse sequence, using the reference template pulse sequence; and

    a comparator which compares the pulse sequences for the signal 0 and the signal 1 based on the start point information regarding the random number sequence with the received random-interval pulse sequence, and determines whether the value of the received random-interval pulse sequence is 0 or 1.
