Problems solved by technology

[0003] In the digital signal transmission system, the method to improve the system capacity includes high-order modulation, such as PAM4 or PAM16 modulation on the digital signal, but in the high-order modulation, the digital signal will be subject to nonlinear interference, resulting in a decrease in the signal quality of the digital signal
[0004] In the prior art, the digital signal can be compensated by the Volterra series model. For example, the nonlinear compensation of the digital signal can be performed by the Volterra series model. Non-linear compensation of all digital signals requires a huge amount of calculation, resulting in huge consumption of resources and power consumption

Abstract

The embodiment of the invention discloses a digital signal processing method. The method comprises the steps that digital signal processing equipment receives a first digital signal; when that the first digital signal is in a first area is determined, the digital signal processing equipment carries out signal compensation on the first digital signal, the first area is an intersection area of a second area and a third area, the signal value of the digital signal located in the second area is a first signal value, and the signal value of the digital signal located in the third area is a second signal value; the digital signal processing equipment judges a signal value obtained after the first digital signal is compensated so as to determine that the signal value of the first digital signal is the first signal value or the second signal value. In the method disclosed in the embodiment of the invention, the digital signal processing equipment performs selective compensation on the digitalsignal, and therefore the power consumption of signal compensation can be reduced.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular, to a digital signal processing method and device. Background technique [0002] With the development of big data and cloud computing, users have more and more demand for system transmission capacity. Whether it is used as a short-distance service in a data center or a long-distance service in a metropolitan area, higher capacity and lower power consumption, Lower prices have always been the goal pursued by users. [0003] In the digital signal transmission system, the method to improve the system capacity includes high-order modulation, such as PAM4 or PAM16 modulation on the digital signal, but in the high-order modulation, the digital signal will be subject to nonlinear interference, resulting in a decrease in the signal quality of the digital signal . [0004] In the prior art, the digital signal can be compensated by the Volterra series model. For exa...
