Abstract: PURPOSE: A radio transmitting and receiving method for preventing jamming is provided to avoid a collision between transmission signals and heighten the reliability of a radio communication in a radio transmitting and receiving system by allowing a plurality of transmitters to have a random output period to transmit a radio signal. CONSTITUTION: A transmitter includes a data processor(12), a modulator(14), a transmitting RF amplifier(16) and a pseudo random number(PN) sequence generator(50a) for randomly outputting a radio signal transmission period. When then transmitter is operated, 'n' number of consecutive signals are generated by the PN sequence generator(50a) after time of t1. Second 'n' number of consecutive signals of the 'N' period are transmitted after time of t2, the random time. In this manner, the N period of signals are all transmitted At this time, the PN sequence generator(50a) determines a 'tn' by multiplying by the unit time 't' used by a basic clock of the data processor(12). Even though transmitted signals are outputted from more than two transmitters or repeaters of the 'n' number of transmitters and 'm' number of repeaters, the signals do not collide with each other. Thus, the repeater or a receiver receives more than two signals as transmitted and codes them.
