PURPOSE:To operate a repeater in a saturating state by using a spread spectrum so as to apply multiple access processing by means of the frequency hopping and time hopping system, thereby limiting the carrier frequency accessed simultaneously in the repeater to one. CONSTITUTION:A frequency hopping pattern 100 is given to an access controller 8 to apply switching control to a switch 4. Thus, in the signal arrangement in the repeater, a 1st time slot TS1 is a burst signal of a 1st user (1) and its operating frequency is f1 and a 2nd time slot TS2 is a burst signal of a 5th user (5) and its operating frequency is f2. Moreover, a 3rd time slot TS3 is a burst signal of a 2nd user (2) and its operating frequency is f2, a 4th time slot TS4 is a burst signal of a 4th user (4) and its operating frequency is f4 and a 5th time slot TS5 is a burst signal of a 3rd user (3) and its operating frequency is f5. Then the carrier frequency accessed simultaneously is limited to one carrier frequency. Thus, the repeater is operated in the saturating state. |
