System and method for transmitting/receiving a signal in a communication system

摘要

Disclosed is a method for transmitting a signal in a signal transmission system, which includes demultiplexing a bit stream to be transmitted into a first bit stream and a second bit stream; generating a first coded bit stream by coding the first bit stream according to a first coding rate and generating a second coded bit stream by coding the second bit stream according to a second coding rate; and generating a coded symbol by concatenating the first coded bit stream and the second coded bit stream.
