Method and apparatus for information block encoding and synchronous detecting

Abstract

The invention relates to the communication field, and discloses a method of information block coding and synchronous detection and a device thereof. The information block coding and the synchronous detection are carried out according to a synchronous character sequence meeting special conditions, and the method of the information block coding and the synchronous detection and the device thereof can effectively reduce probability of synchronization errors. The invention further provides an optimal synchronous character sequence within different lengths, and further reduces the probability of synchronization errors.

Description

Method and device for information block coding and synchronization detection technical field The invention relates to the communication field, in particular to information coding and synchronous detection technology. Background technique With the continuous development of communication technology, users have higher and higher requirements for various service qualities such as communication capacity and speed. Since the access network is one of the most technically challenging areas in the entire telecommunication network, in order to meet the increasing bandwidth requirements of users and realize the high-speed, broadband and intelligent access network, various access technologies emerge in an endless stream appear. Among them, the most promising one is the passive optical network (Passive Optical Network, “PON” for short) technology, especially the Ethernet Passive Optical Network (Ethernet Passive Optical Network, “EPON” for short) technology. The main features of EPO...
