Abstract

The invention discloses a frame synchronization method and device; the method comprises the following steps: using the shortest frame length as an initial peak search period, wherein the shortest frame length is selected from possibly emitting frame structures of all emission ends; determining a first maximum correlative value position in the first peak search period, determining the start position of a second peak search period according to a preset protection interval and the first maximum correlative value position, and determining a second maximum correlative value position in the second peak search period; determining the frame length of the received frame according to the second maximum correlative value position, the shortest frame length and the preset protection interval; determining the frame header position of the next frame according to the frame length, and entering the frame synchronization synchronous locking state. A link building process before the frame synchronization locking in the prior art is strong in restrictions, so frame synchronization locking cannot be well realized, and the system is low in performance; the frame synchronization method and device can well solve said problems.

Description

technical field [0001] The invention relates to the communication field, in particular to a frame synchronization method and device. Background technique [0002] In today's society, the demand for wireless data transmission is growing rapidly, and wireless communication technology is also developing rapidly. In order to improve the transmission capacity and transmission rate of the wireless communication system, several methods commonly used at present are frequency diversity, space diversity and the use of polarized antennas. In order to illustrate the technical background of the present invention, the microwave LoS (Line of Sight, Light of Sight) MIMO (multi-antenna technology, also known as multiple input multiple output technology, Multiple Input Multiple Output) system is taken as an example here, and the prior art exists problem is explained. [0003] Microwave transmission has the advantages of high speed, high stability, and less land resource occupation. Microwav...
