ADJUSTING ORTHOGONAL FREQUENCY DIVISION MULTIPLEXED WAVEFORMS USING SELECTED SUBCARRIERS

In some embodiments, a method for multiplexing signals can include providing multiple subcarriers, selecting a group of one or more subcarriers among the multiple subcarriers, and adjusting each subcarrier of the selected group. The method can further include performing a multiplexing operation with the multiple subcarriers to obtain an output signal, with the output signal having an adjusted property resulting from the adjusting of the one or more subcarriers of the selected group. In some embodiments, the multiple subcarriers can include one or more groups of data subcarriers and one or more groups of guard band subcarriers.
