摘要：A system for crest factor reduction (CFR) includes a peak detector configuredto receive an input signal (xk); a running maximum filter configured to generate a scalingfactor based on a window gain (Gk) and a filter length, wherein the window gain (Gk) isbased on the input signal (xk) and a threshold value (T); a window CFR gain filterconfigured to generate a gain correction (Fk) based on the scaling factor and the filterlength; a delay configured to delay the input signal (xk) to generate a delayed inputsignal; a multiplier configured to multiply the gain correction (Fk) by the delayed inputsignal to obtain a peak correction value; and an adder configured to determine an outputsignal (yk) based on the peak correction value and the delayed input signal.
