    • There is provided a system for communicating information, comprising: a transmitter comprising an encoder including a classifier for classifying coded information bits into systematic bits and parity bits, a first modulator for modulating the systematic bits by a lower order modulation, a second modulator for modulating the parity bits by a higher order modulation, and a combiner for combining the modulated systematic bits and parity bits; and a receiver comprising a decoder including a divider for dividing received symbol estimates into a systematic group and a parity group, a first demodulator for demodulating the symbol estimates of the systematic group by a lower order demodulation, a second demodulator for demodulating the symbol esti mates of the parity group by a higher order demodulation, and a second combiner for combining the demodulated symbol estimates.
    • 提供了一种用于传送信息的系统,包括:发射机,包括编码器,包括用于将编码信息比特分类为系统比特和奇偶校验比特的分类器,用于通过较低阶调制调制系统比特的第一调制器,用于调制 通过较高阶调制的奇偶校验位,以及用于组合调制的系统位和奇偶校验位的组合器; 以及接收机,包括:解码器,包括用于将接收到的符号估计分成系统组和奇偶校验组的分频器;第一解调器,用于通过低阶解调来解调系统组的符号估计;第二解调器,用于解调符号估计 以及用于组合解调的符号估计的第二组合器。
