Frequency domain pulse position modulation
An apparatus of a wireless device has a storage element to store data from a first data stream and a second data stream and a processing component operatively coupled to the storage element. The processing component selects a first set of data from the first data stream to be transmitted and determines one or more subcarriers of a plurality of available subcarriers to transmit at a first power level to represent the first set of data. The processing component also selects a second set of data from the second data stream and encodes the second set of data at a second power level on a set of remaining subcarriers that are not to be transmitted at the first power level. The processing component may then generate a symbol to be transmitted comprising the plurality of subcarriers.
