Abstract:
Accordingly, systems and methods for managing power when the number of training and data tones are increased in a wireless communications system are provided. An L-SIG field is generated that includes a set of data and pilot tones, wherein the pilot tones are inserted between the data tones in the set of data and pilot tones. A plurality of training tones is added to the L-SIG field before and after the set of data and pilot tones. A symbol is generated that includes the L-SIG field, an L-LTF field, and a data field, wherein the training tones of the L-SIG field provide channel estimates for the data field. Power of the L-LTF field is managed relative to power of the L-SIG field in the generated symbol in a time domain.
