Abstract

The invention provides a coefficient updating method, an equipment receiving end, an equipment sending end and a system, which are suitable for a quick training process and comprise the following steps of: S1, judging whether a current link meets a starting coefficient updating mode or not; if so, executing the step S2; if not, returning to the step S1; s2, the sending end maintains the current THP coefficient; s3, the receiving end opens a decision feedback equalizer, and processes the current DFE coefficient and the last DFE coefficient to obtain an updated THP coefficient; and S4, the sending end uses the updated THP coefficient sent by the receiving end, closes the decision feedback equalizer at the same time, continues to keep the link stable and returns to the step S1. The technical scheme has the beneficial effect that a brand-new coefficient updating method is provided for opening a THP training scene in a quick training process.

Description

technical field [0001] The invention relates to the technical field of communication, and in particular to a coefficient updating method suitable for a fast training process, a device receiving end, a device sending end and a system. Background technique [0002] 10G / 5G / 2.5G Ethernet PHYs all introduce THP technology (THP (Tomlinson-Harashima Precoding): Tomlinson-Harashima Precoding), which sends the DFE (Decision Feedback Equalizer) coefficients at the receiving end to the sending At the end, the sending end copies the received coefficients to the THP module. This technique avoids possible error propagation at the receiving end. However, for the scene where THP training is turned on during the fast training process, there is a lack of an effective coefficient training method that can maintain link stability. Contents of the invention [0003] In view of the lack of an effective coefficient update method in the scene where THP training is turned on during the fast train...
