Problems solved by technology
[0004] However, the currently used pre-emphasis technology belongs to fixed pre-emphasis, that is, the pre-emphasized high-frequency energy in the transmission signal is fixed and does not depend on the change of the input signal, so it is impossible to optimize the pre-emphasized high-frequency energy, resulting in communication low quality

The invention relates to the technical field of communication, and discloses a communication quality optimization method and device based on pre-emphasis, equipment and a storage medium; the method comprises the steps: obtaining the duration of a level signal before an edge to be pre-emphasis; obtaining a pre-emphasis energy value according to the duration; and performing pre-emphasis on the edge according to the pre-emphasis energy value. The invention provides a communication quality optimization method and device based on pre-emphasis, equipment and a storage medium. The pre-emphasis energy value is controlled in a closed-loop manner according to the duration of the level signal, and then the signal is pre-emphasis according to the dynamically obtained pre-emphasis energy value, so that the pre-emphasis performance can be improved; meanwhile, the eye pattern quality of the pre-emphasis signal is improved, the inter-symbol interference is reduced, and the communication quality is optimized.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a communication quality optimization method, device, equipment and storage medium based on pre-emphasis. Background technique [0002] Due to the bandwidth limitation of the transmitting device and the receiving device, the line loss of the PCB board level and the loss of the optical fiber line, etc., the optical fiber number emitted by the laser is transmitted through the output of the driver, the transmission of the circuit on the PCB board, the emission of the laser and the transmission of the optical fiber line. After that, the optical signal will show a certain attenuation. Among them, the wiring loss and material loss have frequency characteristics, that is to say, the attenuation of the signal by the wiring on the PCB, the optical fiber line, the parasitic of the laser and the driver increases with the increase of the optical signal frequency. In other word...
