Abstract

The invention discloses a frame synchronization method and device oriented to blank frame transmission. The sending end sends a blank frame when the amount of data is insufficient, and utilizes the feature of weak correlation between different frame synchronization sequences to make blank frames and non- Blank frames carry different frame synchronization sequences, and the receiving end can distinguish blank frames from non-blank frames by performing cross-correlation processing on different frame synchronization sequences, complete the synchronization process, and enable the subsequent communication process to work normally, realizing continuous data transmission , which ensures that the equalization module at the receiving end can continuously track and improves system performance, and because the system continuously transmits data, the receiving end does not need to store a large amount of data and use a large amount of logical resources for frame synchronization, which reduces the complexity of the system. Therefore, the frame synchronization method oriented to blank frame transmission provided by the present invention solves the technical problems of high system complexity of the existing burst transmission technology for distinguishing blank frames and difficulty in maintaining continuous data transmission, resulting in reduced overall system performance.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a frame synchronization method and device for blank frame transmission. Background technique [0002] With the continuous development of wireless communication technology, people's demand for transmission rate is also constantly changing, resulting in a mismatch between the actual demanded rate and the system speed. When the system rate is greater than the actual demanded rate, the system will have no data to send , so there is a blank frame. Identifying and removing blank frames increases the difficulty of system frame synchronization and reduces the performance of the system equalization module. [0003] At present, one of the technologies used to combat blank frames is the burst transmission technology. The main idea of ​​the burst transmission technology is that the sender judges whether there is enough data for sending before transmission, and if so, sends th...
