Abstract

Embodiments of the present invention provide a lead code sending method and device, and a lead code receiving method and device. The sending method comprises the steps: sending a lead code comprisingtwo or more code pattern sequences, wherein the two or more code pattern sequences comprise a first code pattern sequence and a second code pattern sequence; according to the invention, the lead codesare enabled to support different code pattern sequences, and functions corresponding to the different code pattern sequences are utilized to realize rapid transmission of the lead codes, thereby realizing rapid balanced convergence after the rate of the passive optical network is improved, improving the transmission efficiency and reducing the processing time delay. By adopting the technical scheme, the problems of long equalization time, reduction of transmission efficiency, increase of processing time delay and the like due to the fact that lead codes are not beneficial to convergence of anequalizer in related technologies are solved.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, relate to a method and device for sending a preamble, and a method and device for receiving a preamble. Background technique [0002] At present, in the prior art, the uplink of PON (Passive Optical Network, PON for short) adopts time division multiple access technology, and different ONUs (Optical Network Unit, optical network unit, ONU for short) send uplink bursts at different times. When sending a signal, OLT (Optical Line terminal, OLT for short) must first perform burst clock recovery on different burst packets when receiving, and the data cannot be received normally before the clock recovery is completed. In order to prevent data loss during this period, At the beginning of the uplink burst packet, a 1010 sequence is sent for clock recovery. [0003] After the PON rate increases, the bandwidth of the device is insufficient, and different factors such as r...
