Abstract
Systems and methods are provided for broadcasting a for broadcasting a modulated signal. A plurality of peaks is detected within a waveform envelope signal of the modulated signal. For each of the plurality of peaks, a pulse having substantial spectral content that is outside of a passband of a high power filter is constructed. The constructed pulse for each peak is subtracted from its associated peak to provide a peak-reduced signal. The peak-reduced signal is amplified at a power amplifier to provide an amplified signal. The amplified signal is filtered at the high power filter to provide a filtered signal. The filtered signal is broadcast at an associated antenna.
