Abstract
Provided are a system and method of generating a wake up signal, the method including receiving plurality of input samples; performing subcarrier mapping that maps the plurality of input samples to a set of subcarriers, thereby generating a subcarrier mapper output; generating a first orthogonal frequency-division multiplexing (OFDM) signal by mapping at least a portion of the subcarrier mapper output to a first frequency band that corresponds to a first wake up signal symbol; generating a second OFDM signal by mapping at least a portion of the subcarrier mapper output to a second frequency band that corresponds to a second wake up signal symbol; and generating a wake up signal comprising at least a portion of the first OFDM signal to represent the first wake up symbol and at least a portion of second OFDM signal to represent the second wake up signal.
