ABSTRACT:
A digital radio communications receiver for determining a frame structure even in the event of miss or false detection of a frame structure flag. The receiver, for use in a digital communications stem having two or more frame structures, comprises unique word detector module for detecting a unique word from a received bit string, a receive timing controller for timing controlling a received frame based on the unique word detection information from the unique word detector module, a frame synchronization determining module for determining the establishment of the synchronization of the received frame based on the unique word detection information from the unique word detector module and the frame synchronization guard level and for outputting the determination results as frame synchronization information, and a frame structure determining module for determining the frame structure based on the unique word detection information from the unique word detector module and for outputting the determination results as frame structure information, whereby the frame structure is predicted based on the intervals and phase of the unique words without the need for determining the frame structure flag.
