Abstract: PURPOSE:To always obtain an accurate demodulation data and to ensure the interruption processing by an interruption data by selecting a frequency of same network excellent in a reception data. CONSTITUTION:In the standby state of TA interruption, a group, block error detection circuit 12 detects an out of synchronism.
