RADIO CHANNEL MULTIPLEX COMMUNICATION SYSTEM IN CDMA MOBILE COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To secure the large number of radio channels without increasing a used frequency by using a slot synchronizing signal generated through the use of a reference clock signal obtained from a GPS reception signal for the synchronization of the time slots of a base station and respective mobile equipments. SOLUTION: A time division/multiplex signal where a frame formed of plural time slots is repeated is used for a communication signal. The respective time slots of the time division/multiplex signal are allocated to different radio channels. Communication signals 71 and 72 to a mobile equipment 40 or from the mobile machine 40 use a time slot TS0, communication signals 81 and 82 to a mobile equipment 41 or from the mobile equipment 41 use a time slot TS1 and communication signals 91 and 92 to a mobile equipment 42 or from the mobile equipment 42 use a time slot TS2, for example. A means for using a slot synchronizing signal generated by using a reference clock signal obtained from the GPS reception signal for synchronizing the time slots of the base station 30 and the respective mobile equipments 40-42 is installed.
