Equalization circuit, communication method, and communication apparatus

Abstract

Embodiments of the present application relate to the field of communications, and provide an equalization circuit, a communication method, and a communication apparatus, used for achieving real‑time and automatic adjustment of system flatness on the basis of dynamic scenario changes. In the method, a first device may, on the basis of acquired flatness information, perform amplitude equalization on a first signal within a first bandwidth by means of P equalization sub‑circuits, separately, so as to obtain P equalized signals, and then superimpose the P equalized signals to obtain an equalized signal. The flatness information is used for indicating an amplitude change of a second signal within the first bandwidth. In other words, the flatness information may be used for indicating real-time system flatness. In this way, the first device may dynamically and automatically adjust the system flatness in real time on the basis of the flatness information, so as to implement automatic amplitude equalization of signals (such as the first signal) within the first bandwidth.
