Abstract
A mobile communication system implementing a frequency sharing and a time slot sharing using communication signal including a plurality of TDMA signals and/or the time divided CDMA signals, to supply the mobile communication system with an improved overall communication quality. The system includes the communication signal from a plurality of multiple access method for sharing frequency and time. A TDMA signal identified by synchronization word code has a different synchronization word code from each other, which is assigned to the same frequency and time slot. A time divided CDMA signal is frequency spreaded by spreading codes which is assigned to time divided time slot. The system also includes the stations which regenerate the time divided CDMA shared signal from the received communication signal and after a removal of the shared signal from the communication signal the TDMA signal synchronization word code is regenerated as desired signal.
