1. , a kind of digital multimedia receiver that is used for the signal of processing single-carrier modulated signals and multi-carrier modulation comprises:

  • Tuner, be used for the multi-media signal that will receive be tuned to corresponding band;

    ADC, being used in the future, the tuning conversion of signals of self-tuner is a digital signal;

    Demodulating unit comprises being used for carrying out the single carrier demodulation device of demodulation with the single carrier mode digital signal corresponding and be used for the multicarrier demodulator that carries out demodulation with multi-carrier modulation pattern digital signal corresponding from ADC from ADC;

    Selector is used for selecting one according to the modulating mode indication from the signal of single carrier demodulation device and the output of multicarrier demodulator;

    WithThe shared channel decoder, being used for will be from the signal decoding and the output of the demodulation of selector output.
