Abstract

The embodiment of the invention provides a method and device for determining a parameter. The method comprises the following steps: determining a first compensation value of a signal needing to be sent by a sending circuit; determining a pre-emphasis parameter needing to be used when the sending circuit sends the signal according to the first compensation value. Compared with the prior art, the technical scheme provided by the invention can flexibly determine the pre-emphasis parameter.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a method and device for determining parameters in the communication field. Background technique [0002] Transmitting circuits and receiving circuits are components in a network device. Network devices communicate through transmitting and receiving circuits. For example, router 1 sends a packet to router 2 through the sending circuit. Router 2 receives the packet sent by Router 1 through the receiving circuit. A serializer / deserializer (Serializer / Deserializer, Serdes) is an interface for realizing high-speed communication. Serdes can be applied in network devices such as routers and switches. For example, a serializer may be included in the transmission circuit of the router 1 . The deserializer may be included in the receiving circuit of the router 2 . [0003] In order to improve the signal-to-noise ratio of the transmitted signal, the transmitting circuit may ...
