| Abstract: | DRM＋ is the standard for digitizing analog broadcast by DRM group,which is the only universal standard of the digital broadcasting covers on the ultrashort wave to long wave band.introduces The advantages of DRM＋ digital frequency modulation broadcasting system is given,and the implementation procedure of digital signal processing is proposed.The appropriate schemes for signal synchronization,demodulation,channel estimation,channel decoding source decoding are finished,and program is done to output the the original broadcast signal.The SNR and constellation figure are given by MATLAB,which verifies that this method is correct. |
