Multi-Rate Crest Factor Reduction - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17760197 Titled 'Multi-Rate Crest Factor Reduction'
Simplified Explanation
The abstract describes a computer-based method for reducing crest factor, which is a measure of the peak-to-average ratio of a signal. The method involves receiving a set of input samples, performing peak detection on these samples, downsampling the peak detection output, generating windowing output samples, upsampling the windowing output, and generating an output signal based on the original input samples and the peak reduction samples. The goal of this method is to reduce the difference between the highest and average levels of the signal.
Original Abstract Submitted
A computer-implemented method for reducing crest factor by an electronic device includes: receiving a plurality of first samples of a first input signal. The plurality of first samples are generated at a first sampling rate. A first peak detection is performed based on the plurality of first samples to generate a plurality of first peak detection output samples. A plurality of first windowing input samples are generated at a second sampling rate by downsampling the plurality of first peak detection output samples. A plurality of first windowing output samples are generated based on the plurality of first windowing input samples. A plurality of first peak reduction samples are generated at the first sampling rate by upsampling the plurality of first windowing output samples. A first output signal is generated based on the plurality of first samples and the plurality of first peak reduction samples.
