Abstract

PURPOSE:To accommodate newly a subscriber radio system by positioning a frequency arrangement of a large capacity basic line system, in co-channel arrangement generating a frequency band not in use in the basic line system, and opening the band for a short distance communication system such as subscriber radio line. CONSTITUTION:Eight waves 10, 11, 12, 13, 14, 15, 16, 17 are signal spectrums for a radio relay system using multi-channel at regular intervals with co-channel arrangement. On the other hand, 6 slots of 20, 21, 22, 23, 24, 25 are bands not used by the relay system entirely and the spectrum of subscriber radio system of a shortdistance operated by using the band is shown. Thus, the expansion of demand is remarkable and the use of the frequency band used by the large capacity base line is allowed for the radio subscriber system.
