Filtering for detection of limited-duration distortion |
摘要 |
Processing a signal includes: receiving data that includes an input signal; filtering the input signal to generate a filtered signal, such that if the input signal includes at least one instance of a nonlinear distortion of a desired signal then the filtered signal includes a signature signal corresponding to the nonlinear distortion, the nonlinear distortion characterized by a time duration that is within a predetermined range; and detecting whether or not the filtered signal includes the signature signal. |

1. A method for processing a signal, the method comprising:
receiving data that includes an input signal;
filtering the input signal to generate a filtered signal, wherein if the input signal includes at least one instance of a nonlinear distortion of a desired signal, then the filtered signal includes a signature signal corresponding to the nonlinear distortion, the nonlinear distortion being characterized by a time duration that is within a predetermined range; anddetecting whether the filtered signal includes the signature signal,wherein detecting whether the filtered signal includes the signature signal comprises applying a matched filter to the filtered signal. |
