Abstract
Embodiments of the present disclosure relate to a device, a method, an apparatus and a computer-readable medium for signal equalization. According to the embodiments of the present disclosure, a balance between equalization performance and effects is achieved by using a linear equalizer and a nonlinear equalizer. In addition, signals from different uplinks are equalized using adaptive parameters, to achieve optimal equalization of various signals.
