PURPOSE:To establish accurately and easily synchronization at an arbitrary point even in the communication line having a large error rate by an easy detection, namely, discrimination of the second synchronizing signal based on the discrimination result of the first synchronizing signal. CONSTITUTION:Synchronous information of one frame consisting of the first synchronizing signal A of a code, which consists of peculiar code arrangement set previously between the transmission side and the receiving side, and the second synchronizing signal B indicating the position signal of the first synchronizing signal is transmitted periodically prescribed-number times. In the receiving side, when the first synchronizing signal of one frame is detected correctly, signal synchronization is established on a basis of discrimination of the second synchronizing signal, thereby obtaining the communication synchronous system. |
