PURPOSE:To obtain a ground-classified MF phase synchronization for the respective data which are mixedly multiplexed to the same frame by storing information concerning each ground into a storage part, and parallel-processing the multi-frame(MF) phase synchronization at every ground under the control of the storage part. CONSTITUTION:A single frame(SF) system data control circuit 2, plural ground- classified MF phase synchronizing circuits 3b to 3n corresponding to the number of ground, an SF system data control circuit 2, a storage part 4, which stores information to control ground-classified MF phase synchronizing circuits 3b to 3n, and an AND circuit 5 as a multiplexing circuit are provided. For the data on the respective time slots of the received frame, the information, which indicates the relation between each ground allocated by the storage part 4 and the time slot of the data combining the FMs included in the ground is fetched, and the MF phase synchronization for the ground of the respectively allocated data is obtained based on the information. Thus even when the different data are mixed in the same frame, the data can be arranged to the same phase. |
