PROBLEM TO BE SOLVED: To effectively use a radio frequency in a radio transmitting system and its application system, to reduce power consumption, to efficiently form a radio transmission line through the use of simple hardware and to effectively use the characteristic. SOLUTION: Plural transmitters 111 -11M to which plural unique prime numbers are allocated, which have pulse width less than a unit period at a repetitive period equal to the product of the unit period and the prime number thereof and transmit burst waves where the radio frequencies are the same, and a receiver 12 provided with a demodulation means 13 which amplitude-demodulates received waves arrived from the transmitters and generates a pules train and with transmission channel identification means 141 -14N which individually take correlation between an examination pulse train whose period is equal to the product with the unit period and whose pulse width is less than the period, and the pulse train that the demodulation means 13 generated and which output the results are provided.
