Abstract
Provided is a technology applicable to a broad signal to noise ratio (SNR) environment for a satellite communication and broadcasting service, including a mapper to modulate a forward error correction frame based on a predetermined constellation, a physical layer header processor to add a physical layer header to the modulated forward error correction frame, a physical layer frame spreader to spread a physical layer frame of the modulated forward error correction frame, and a physical layer scrambler to scramble the added physical layer header and the spread physical layer frame.
