Title:
増幅されるべき信号を含む通信システムにおいて使用するための方法および増幅されるべき信号を処理するための方法および増幅されるべき信号のピークを制限するためのシステム
Document Type and Number:
Japanese Patent JP4436545
Kind Code:
B2
Abstract:
A signal notching system reduces signal peaks by notching the peak of a signal above a threshold to produce a notched signal. The notched signal is then filtered to produce a resulting signal with a reduced peak amplitude. For example, in an implementation where the signal is represented by signal samples, the peak notching system first locates a peak sample that is beyond a threshold, such as a sample representing a positive peak sample of a peak above the threshold. Once a peak sample is located, the peak notching system adjusts the peak sample by an amount which is a function of the amount that the peak sample is beyond the threshold, effectively creating a notched signal with a one sample notch at the peak. The peak notching system filters the notched signal to fill in the notch to produce a signal with a reduced peak.
