Abstract
A method for reducing probability of clipping in an IFFT-based (inverse fast Fourier transform based) multitone communication transmitter, the method including applying an IFFT to an original sequence thereby to generate an IFFT output sequence, if the IFFT output sequence fits a predetermined clipping profile, applying at least one transformation to the IFFT output sequence, thereby to define a transmitted sequence, the transformation-applying step including decomposing the IFFT output sequence into a first component sequence and a second component sequence, rearranging at least one of the first and second component sequences with respect to the other, thereby to define third and fourth component sequences, and combining the third and fourth component sequences into a final output sequence.
