摘要： A method for generating OFDM signals is implemented in a device operating according to a communication protocol. The protocol defines non-duplicate mode data units corresponding to single component channels of a BSS channel, and non-duplicate mode data units corresponding to sets of adjacent component channels. Non-duplicate mode data units corresponding to a set of component channels have more lower-edge and/or upper-edge guard tones than non-duplicate mode data units corresponding to single component channels. The method includes determining that a duplicate mode will be utilized for an OFDM transmission in the set of component channels and, in response, generating a duplicate mode data unit. The duplicate mode data unit has fewer lower- edge and/or upper-edge guard tones than a non-duplicate mode data unit corresponding to a set of component channels, and includes one duplicate of the non-duplicate mode data unit corresponding to the single component channel for each adjacent component channel.
