摘要

"METHOD OF GENERATING JAMED SIGN, METHOD OF JAMPING SYMBOLS IN DATA TRANSMISSION SYSTEM". A simplified scramble scheme that unifies all signals of a satellite transmission system, including frame header, frame body and pilot symbols in a common reference phase. This results in further simplification and flexibility of the receiver front end model without affecting overall system performance. In many current frame header and pilot symbol communication systems, the phases of the frame headers and pilot symbols are not designed to be aligned with any data constellation points modulated from the frame body. This scramble scheme considers possible impact due to irregular phase changes between frame headers / pilot symbols and modulated data.
