Method and Apparatus for Peak-to-Average Ratio Reduction |
摘要 |
Peak-to-average ratio reduction is achieved by detecting peaks in an original analog signal that exceed a given threshold. Segments of the original analog signal containing such peaks are treated (e.g., by attenuation) and a composite analog signal is assembled that includes treated and untreated segments of the original analog signal. The composite analog signal is processed to perform analog-to-digital conversion to generate a composite digital signal. Segments of the composite digital signal corresponding to the treated segments of the original analog signal are reverse-treated or otherwise treated again to undo treatment of the segments of the original analog signal. A final output digital signal is generated that corresponds to the original analog signal in digital form. |
