Abstract
The present disclosure provides a device () of crest factor reduction for a multi-carrier signal. The device () includes: a peak detector () adapted to receive a sampled representation of the multi-carrier signal, detect a peak from the sampled representation and obtain a value and a time domain location of a cancellation peak for cancelling the peak; a plurality of peak cancellation signal generators () each corresponding to a carrier of the multi-carrier signal and adapted to generate a peak cancellation signal within a frequency band of its corresponding carrier based on the value and time domain location of the cancellation peak; and a subtractor () adapted to subtract the peak cancellation signals from the sampled representation after being delayed. The present disclosure also provides another device of crest factor reduction, a multi-stage crest factor reduction circuit and a peak detector.
