METHODS, DEVICES AND SYSTEMS FOR MODIFYING A POWER PROFILE OF A FREQUENCY DIVISION MULITPLEXED SIGNALS

A method can include receiving a plurality of digital data symbols; encoding each data symbol into frequency domain values, the frequency domain values for each data symbol transmitted over a different frequency range; combining samples of multiple frequency domain values into a sequence of initial output values in time; generating a sequence of modification values that form a modification pulse, the modification pulse having a non-linear slope that decreases as it approaches a modification pulse maximum and increases as it departs from the modification pulse maximum; decreasing the initial output values according to the modification values to generate modified output values; and transmitting a wireless signal compatible with at least one IEEE wireless standard according to the modified output values. Corresponding devices and systems are also disclosed.
