High-order modulation signals equalization based on reservoir computing under equivalent-time sampling

For digital signal testing and analysis using a sampling oscilloscope, signal equalization of different frequency components is a difficult task. The discontinuity of the sampling points induces the idea that the equalizers based on high-pass filtering cannot be utilized. In this work, an artificial intelligence equalizer based on reservoir computing (RC) is introduced for processing equivalent-time sampling data of high-order modulation signals. The equalizer is established for the in-phase and
