The circuit includes an IFFT (inverse fast fourier transform) block. The IFFT block generates a modulated signal in response to a data signal.

A first subtractor is coupled to the clip logic block and the IFFT block, and subtracts the modulated signal from the clipped signal to generate an error signal. A cyclic filter is coupled to the first subtractor, and filters the error signal to generate a filtered error signal. A second subtractor is coupled to the cyclic filter and the IFFT block.
