Abstract：
The invention discloses a self-adaptive equalization method and system for a high-speed serial port transceiver. The method comprises the following steps: firstly, constructing a data training set containing channel data, equalization coefficient data, a high-speed serial port model and an error rate obtained by model simulation; training an algorithm of a high-speed serial transceiver equalization system by using the data training set; downloading the trained algorithm into a processor of a high-speed serial port chip; and finally, when the high-speed serial port is applied, the processor uses an equalization algorithm to carry out adaptive adjustment on an equalization system of the high-speed serial port transceiver to obtain an optimal equalization effect of the whole transceiver. According to the method, a limited data training set is used, a fitting algorithm is obtained by training a neural network, optimal configuration can be carried out on balancing systems of multiple high-speed serial transceivers in practice by using the algorithm, and the method has the characteristics of wide application range and good balancing effect.
