1. a generation method for frequency-domain OFDM symbol, is characterized in that, comprise the steps:

  • Frequency domain generates fixed sequence program and signaling sequence respectively;

    Fixed sequence program and signaling sequence are filled on effective subcarrier, and the arrangement in oem character set between described fixed sequence program and signaling sequence;

    Null sequence subcarrier is filled respectively to form the frequency-domain OFDM symbol of predetermined length in described effective subcarrier both sides.
