DATA FRAME FORMAT FOR VARIABLE SIZE DATA CONSTELLATIONS

摘要

A data frame structure for variable size data constellations includes repetitive data segments each containing a fixed number of symbols arranged as a data segment sync character and data bytes. The frame includes a header segment including a frame sync code and a data constellation size code for the data frame. The data frame incorporates error correction groups and the frame size is selected to produce an integral number of error correction groups and data bytes in each frame for all of the variable size data constellations.
