Description

A method and system for setting an optimal balance value

technical field

The invention relates to the field of communication technology, in particular to a method and system for setting an optimal equalization value.

Background technique

With the continuous improvement of signal transmission rate, there are more and more problems affecting the signal quality, especially for microstrip lines, the change of the working environment is equivalent to the change of the medium of the microstrip line, that is, the change of the dielectric loss angle. This change will cause a change in the impedance of the microstrip line, resulting in a change in the loss of the microstrip line. In the prior art, channel equalization technology is usually used to compensate signal loss, and channel equalization technology refers to an anti-fading measure taken to improve the transmission performance of a communication system in a fading channel. It is mainly to eliminate or weaken the problem of intersymbol interference (ISI) caused by multipath delay in broadband communication. As an important means of channel compensation in high-speed systems, equalization technology has been widely used in high-speed system design.

In the channel equalization technology, the setting of the equalization value in the equalizer is directly related to whether a high-speed system can work normally, and whether the signal receiver can correctly receive the signal transmitted by the signal transmitter. The method of setting the equalization value of the equalizer that is commonly used now is based on simulation and measurement. The channel is simulated or measured under specific laboratory environmental conditions to select the optimal equalizer value. . But this method has certain limitations. Because the equilibrium value obtained by this method is relatively simple, and this equilibrium value is the initial setting of the system, it will not change with the influence of the environment, and it has no adaptability to environmental changes. However, in practical applications, as the environment changes, the signal The dielectric loss angle of the channel is also changing, and the impedance and loss of the channel will change. In addition, the optimal balance value under the simulation and measurement conditions (laboratory environment) may not be the optimal balance value in the actual operating environment of the system. For high-speed signals, this difference may cause the system to not operate properly. It can be seen that the method for setting the equalization value in the equalizer in the prior art will cause disadvantages such as poor signal reception effect and stability of the signal transmission system.

Therefore, how to provide an optimal equalization value setting method and system that solves the above-mentioned shortcomings of the prior art is a problem that those skilled in the art need to solve.
