FRAME SYNCHRONIZATION METHOD

摘要

The problem of pulse frame synchronization occurs for example in a telecommunications system with cordless terminals operating according to the DECT standard. To establish a radio connection between base station and a cordless terminal, the base station scans its radio cell in sequence with the available ten high-frequency carriers in the DECT frame rhythm. In a multiple cell environment, the synchronization of all base stations belonging to a cordless telecommunications installation is necessary, to enable all base stations to scan the same frequency at the same time. This is achieved by blanking the DECT multiframe synchronization pulses. The pulse gap is evaluated by error detection circuits which are present anyway, and used for the PSCN Primary receiver Scan Numbersynchronization.
