Zusammenfassung:In the disclosed OFDM system, the signal emission method is applying the emission end to send system message on the last OFDM signal of one or more sub-frame; the subzone search method comprises: synchronizing, extracting identity signal to recognize the optimal subzone, demodulating system message, and synchronizing the OFDM signal. This invention improves demodulation performance, and saves search time.
