ABSTRACT:
Block coded digital data is communicated with associated overhead data in a data stream having a succession of coded blocks. Each block contains N symbols wherein M of the symbols comprise information to be transmitted and the remaining N-M of the symbols comprise error correcting data. The ratio M/N comprises a first information rate. The coded blocks in the data stream are divided into a succession of frames, each comprising F of the coded blocks. A frame overhead symbol is added for each of the frames, to provide the data necessary for a receiver function such as synchronization. The addition of the frame overhead symbols effectively lowers the first information rate to a second desired information rate. A plurality of X of the frames are formed into a superframe containing FX coded blocks and associated frame overhead symbols. X is chosen to provide enough n-bit frame overhead symbols to implement the desired receiver function.
