ABSTRACT:
A DSSS and OFDM two-way waiting reception method is disclosed. The reception method includes the steps of (a) maintaining a two-way waiting state if none of an RSSI trigger, an OFDM search trigger, and a DSSS search trigger is generated; (b) switching to an RSSI-activated OFDM reception state if the RSSI trigger is generated in the two-way waiting state; (c) switching to a DSSS reception state if an OFDM synchronization loss trigger is generated in the RSSI-activated OFDM reception state; (d) switching to an OFDM search-activated OFDM reception state if the OFDM search trigger is generated in the two-way waiting state; (e) switching to the DSSS reception state if the DSSS search trigger is generated and the OFDM synchronization loss trigger is generated in the OFDM search-activated OFDM reception state; and (f) switching to the DSSS reception state if the DSSS search trigger is generated in the two-way waiting state.
