Abstract:
1. A method for transmitting data in a communication or broadcasting system, comprising: generating a codeword by encoding input information data bits; interleaving the codeword; demultiplexing the interleaved codeword using a bit-mapping table that is determined based on a modulation scheme and a coding rate; outputting a modulation signal by modulating the demultiplexed bits; and transmitting the modulation signal, wherein when the modulation scheme is 16-Quadrature Amplitude Modulation (16-QAM) and the coding rate includes one of ⅕ and ¼, the bit-mapping table is defined as: where the “input bit number” represents an input bit number d i in the interleaved codeword v d , and the “output bit number” represents a demultiplexed substream value e in the demultiplexed bits b e,d .
