Document Type and Number:
Japanese Patent JP3534763
Kind Code:
B2
Abstract:
A speech signal is transmitted over a radio path by a mobile station, and is received in a first base station. The speech signal, encoded using encoding parameters, is forwarded in the information frames from the first base station to a remotely located speech decoder. Each of the information frames carries a synchronization word and a synchronization check bit recurring at predetermined intervals within the information frame. The information frames are received at the remote speech decoder. The remote speech decoder is synchronized with one of the received information frames using the synchronizing word. Speech encoding parameters are extracted from the received information frames, and the recurring synchronization check bit is monitored within the received information in order to detect an error in the recurring synchronization check bit in the received information frames.
