Peak factor minimization using a time-frequency domain swapping algorithm
E. Van der Ouderaa, Johan Schoukens, Jean Renneboog · IEEE Transactions on Instrumentation and Measurement · 1988
An algorithm is presented to minimize the peaks in the time domain of bandlimited Fourier signals. This method has the ability to compress signals effectively without disturbing their spectral magnitudes. A computationally efficient algorithm is presented that leads to strongly compressed signals (crestfactors of 1.41 compared to 1.67). The method is applicable not only to flat spectrum magnitudes but to any frequency domain energetic distribution.>
