The present disclosure provides a channel optimization method and device, system, electronic equipment and program product. The method comprises: obtaining a channel frequency response value of a target channel based on current state information of a feedforward equalizer of a receiving end of the target channel in a serial system, the channel frequency response value being used to represent transmission quality of different frequency band signals in the target channel; generating an adjustment instruction of a target parameter based on the channel frequency response value, the target parameter being a parameter in a channel before the feedforward equalizer in the target channel; and adjusting the target parameter based on the adjustment instruction of the target parameter, so that the target channel transmits serial signals with the adjusted target parameter. The embodiments of the present disclosure can reduce the time and cost of channel optimization, and help to reduce the bit error rate of the channel and improve the stability of the channel.

The present invention relates to a method and a control device (10) for controlling a display device (8) through a network (NT2) of the low-voltage differential transmission type, called LVDS, in a vehicle (2), said control device (10) being connected to a serial system network (NT1), called CAN network, of the vehicle (2). The method comprises, in response to a first activation command received from the CAN network (NT1), triggering an initialization phase comprising: a1) initialization of the control device (10); a2) initialization of the display device (8); and a3) deactivation of the LVDS network (NT2). Upon detection that steps a1), a2) and a3) are completed, the LVDS network (NT2) is activated, causing the operation of the control device (10) and the display device (8) in a so-called normal mode. A control of the display device (8) can then be carried out by exchanging functional messages (MSG2) according to the normal mode.Figure for abstract: Figure 1.

This invention belongs to the field of signal processing technology, specifically relating to a jitter analysis method and system for high-speed serial signals. By identifying and separating the data jitter sequence DDJ from the total jitter sequence TIE in a high-speed serial signal, a first jitter sequence containing random jitter data RJ is obtained. A first spectrum is obtained by spectral transformation of the first jitter sequence, and a first power spectrum is calculated from the first spectrum. The total power and root mean square (RMS) value of the random jitter are obtained by calculating a portion of the first power spectrum, thus achieving RMS estimation of random jitter in high-speed serial systems, improving accuracy, and being applicable to signals with various code types. By selectively accumulating power spectrum segments, stable random jitter estimation is achieved, reducing estimation complexity and saving system resources.
