Abstract:
1. A method for transmitting a signal, the method comprising: error-correction-coding service data according to an error-correction coding method; interleaving bits of the error-correction-coded service data, wherein the interleaving comprises: demultiplexing the interleaved bits according to a code rate of the error-correction coding method and one of the symbol mapping methods, wherein an order of outputting demultiplexed bits is different from an order of the interleaved bits when the symbol mapping method is one of 16-QAM, 64-QAM, or 256-QAM, mapping the demultiplexed bits to a symbol; building a signal frame including the mapped symbol; modulating the signal frame according to an orthogonal frequency division multiplexing (OFDM) method; and transmitting the signal including the modulated signal frame via at least one frequency band.
