Problems solved by technology

[0005] This patent also has the following disadvantages: if one of the data channels is disconnected, it is detected that the marker block of the channel has not arrived within the predetermined time, the marker alignment fails, and the buffer operation of the data of each channel is cleared, thus causing other channels. Data also cannot be aligned

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the drawings.

[0030] Such as figure 1 It is a hardware schematic diagram of a sending end of a multi-channel data alignment system based on system synchronization and reference channels according to an embodiment of the present invention; figure 2 It is a hardware schematic diagram of a receiving end of a multi-channel data alignment system based on system synchronization and reference channels according to an embodiment of the present invention. The following is figure 1 , 2 Instructions for the hardware used in:

[0031] AD board: complete the AD conversion of the radar intermediate frequency data, and frame the AD converted data with the "system synchronization".

[0032] Multiplexer board: complete multiplexing of N channel data, 8B10B encoding, parallel-serial conversion and electro-optical conversion.

[0033] Due to the large N, the bandwidth of the serial data after multiplexing, 8B10B encoding...

Abstract

The invention relates to the fields of optical fiber communication and digital communication. Particularly, the invention relates to a method for aligning multichannel data based on a system synchronizing and reference channel. The method for aligning the multichannel data based on the system synchronizing and reference channel comprises the following steps: the transmitted multichannel data are basically synchronized by arranging a ''system synchronization'' signal; then ''reference channel'' data are arranged additionally, so that a read control module for aligning channels is unrelated with the data of the working channel.

Description

Technical field [0001] The invention relates to the field of optical fiber communication and digital communication, in particular to a method for multi-channel data alignment based on system synchronization and reference channels. Background technique [0002] In the phased array radar, during the transmission of multiple channels of AD data, the difference in signal delay is caused by the difference in the length of the signal transmission path. As a result, the problem of aligning multiple channels of data is often encountered in the design process. [0003] The present invention also relates to multiplex technology: the process of combining two or more tributary digital signals into a single combined digital signal in a time division multiplexing manner at the transmitting end of the transmission line is called digital multiplexing; The process of separating a composite digital signal into two or more branch digital signals at the receiving end of the transmission line is called...
