Abstract
Methods and apparatus are provided for transmitting data in a broadcasting system. Input data is encoded by an encoder. A first demultiplexer generates first transmission symbols using the encoded data. The first transmission symbols are modulated, and the modulated first transmission symbols are transmitted. A second demultiplexer generates second transmission symbols using at least a portion of the encoded data. The second transmission symbols are modulated and the modulated second transmission symbols are transmitted.

A method for transmitting data in a broadcasting system, comprising the steps of:
- encoding input data by an encoder;
- generating, by a first demultiplexer, first transmission symbols using the encoded data, modulating the first transmission symbols, and transmitting the modulated first transmission symbols;
- and
- generating, by a second demultiplexer, second transmission symbols using at least a portion of the encoded data, modulating the second transmission symbols, and transmitting the modulated second transmission symbols,
- wherein the first demultiplexer and the second demultiplexer are determined depending on a modulation scheme applied to the first transmission symbols and the second transmission symbols.
An apparatus for transmitting data in a broadcasting system, comprising:
- an encoder for encoding input data;
- a first demultiplexer for generating first transmission symbols using the encoded data;
- and
- a second demultiplexer for generating second transmission symbols using at least a portion of the encoded data;
- a modulator for modulating the first transmission symbols and the second transmission symbols;
- and
- a transmitter for transmitting the modulated first transmission symbols and the modulated second transmission symbols,
- wherein the first demultiplexer and the second demultiplexer are determined depending on a modulation scheme applied to the first transmission symbols and the second transmission symbols.
A method for receiving data in a broadcasting system, comprising the steps of:
- receiving and demodulating coded first transmission symbols and coded second transmission symbols;
- calculating first and second decoder input values for decoding the demodulated first transmission symbols and the demodulated second transmission symbols;
- and
- combining the first decoder input value for the first transmission symbols with the second decoder input value for the second transmission symbols, and decoding the combined decoder input values;
- wherein the first transmission symbols are symbols obtained by demultiplexing a signal by a first demultiplexer, and the second transmission symbols are symbols obtained by demultiplexing a signal by a second demultiplexer using at least a portion of data which is input to the first demultiplexer, and
- wherein the first demultiplexer and the second demultiplexer are determined depending on a modulation scheme applied to the first transmission symbols and the second transmission symbols.
An apparatus for receiving data in a broadcasting system, comprising:
- a demodulator for receiving and demodulating coded first transmission symbols and coded second transmission symbols;
- a calculator for calculating first and second decoder input values for decoding the demodulated first transmission symbols and second transmission symbols;
- and
- a decoder for combining the first decoder input value for the first transmission symbols with the second decoder input value for the second transmission symbols, and decoding the combined decoder input values;
- wherein the first transmission symbols are symbols obtained by demultiplexing a signal by a first demultiplexer, and the second transmission symbols are symbols obtained by demultiplexing a signal by a second demultiplexer using at least a portion of data which is input to the first demultiplexer, and
- wherein the first demultiplexer and the second demultiplexer are determined depending on a modulation scheme applied to the first transmission symbols and the second transmission symbols.
