NON-LINEAR SIGNAL DISTORTION DETECTION USING MULTIPLE SIGNAL TO NOISE RATIO MEASUREMENT SOURCES |
摘要 |
A television signal processing apparatus comprising a receiver comprises a distortion estimator and an automatic gain control signal generator. The automatic gain control signal generator generates a plurality of automatic gain control and filter response control signals in response to the magnitude or signal to noise ratio of an RF signal and a non-linear distortion figure generated from the information carried by said RF signal. The distortion estimator uses a plurality of statistical methods to generate a non-linear distortion figure from the signal constellation of the information carried by said RF signal. |
