Abstract
A waveform communicated from a first station to a second station over the shared medium may be communicated at a time that is based on a shared time reference shared by the first and second stations. The waveform may include at least a first symbol, having a predetermined symbol length, comprising a first set of frequency components at predetermined carrier frequencies modulated with preamble information and a second set of frequency components at predetermined carrier frequencies modulated with frame control information. The carrier frequencies of the first and second sets of frequency components may be integral multiples of a frequency interval determined by the inverse of the symbol length. The first symbol of the waveform may be demodulated in response to detecting a series of values sampled based on the shared time reference.
