  • Publication number: 20220217031
    Abstract: The present application relates to a system and a method for reducing a signal peak-to-average ratio, and a computer-readable storage medium. Before the peaks in the IQ signal are scaled, a scaling effect of peak points scaling on subsequent peak points is estimated and windowing intensities of subsequent peak points are modified. It solves a problem that generated correction coefficients superimpose on top of each other leading to excessive peak shaving. In addition, the above method does not need a lot of multipliers and is easy to be implemented.
