1. a digital radio world wide universal standard (DRM) receiver comprises:

  • AD converter (ADC) is used for the DRM encoded signals that is received with the sampling of first sampling rate;

    Down-sampler is used for the DRM encoded signals that following sampling rate x down-sampling is received, and x is a positive integer herein;

    Mode discriminator, the output of being coupled to down-sampler is used to determine the predetermined DRM parameter mode of the DRM encoded signals that received and the signal of this DRM pattern of determining of output indication;

    Demodulator, be coupled to down-sampler, be used to receive the DRM encoded signals of down-sampling and be demodulated into a plurality of unit, this demodulator also comprises programmable N point fast Fourier conversion (FFT), N is the integer that equals 2 power herein, and N is in response to the signal of the DRM pattern that indication determines and is determined.
