Peak-to-average power reduction using guard tone filtering

A method comprising:

• performing inverse fast fourier transform (IFFT) on a data signal to generate a modulated signal;
• clipping the modulated signal to generate a clipped signal;
• and
• generating a processed signal from the modulated signal and the clipped signal, a peak-to-average power ratio (PAR) of the processed signal is less than a PAR of the data signal.

A computing device comprising:

• a processing unit;
• a memory module coupled to the processing unit;
• and
• a transceiver coupled to the processing unit and the memory module, the transceiver includes a circuit, the circuit further comprising:
• an IFFT (inverse fast fourier transform) block configured to generate a modulated signal in response to a data signal;
• a clip logic block coupled to the IFFT block, and configured to generate a clipped signal in response to the modulated signal;
• and
• a second subtractor coupled to the IFFT block and configured to generate a processed signal in response to the modulated signal and the clipped signal, a peak-to-average power ratio (PAR) of the processed signal is less than a PAR of the data signal.
