Abstract
The present invention provides an apparatus, system and method of peak-to-average reduction of an oversampled signal for a digital communication system. Peak detectionand width measurementare advantageously combined in which a peak portion or multiple peak portions of an input signal that exceeds a predetermined threshold is detected and a width of the peak portion is determined. The peak detection and width measurement are further combined with a novel variable width shape generation methodologyin which a variable width shaping response is appliedto the peak portion responsive to the peak portion width. Additionally, a novel receiver techniquecan be included to reduce or eliminate the upstream BER impact using downstream oversampled shaping.
