Frame synchronization method and device for blank frame transmission

Abstract

The invention discloses a frame synchronization method and device for blank frame transmission, a sending end sends a blank frame under the condition that the data volume is not enough, and the blank frame and a non-blank frame carry different frame synchronization sequences by utilizing the characteristic that the correlation between different frame synchronization sequences is relatively weak, a receiving end distinguishes blank frames and non-blank frames by performing cross-correlation processing on different frame synchronization sequences, completes a synchronization process, enables a subsequent communication process to work normally, realizes continuous transmission of data, ensures that an equalization module of the receiving end can track continuously, and improves system performance, and with continuous data transmission of the system, the receiving end does not need to store a large amount of data and use a large amount of logic resources for frame synchronization, and system complexity is reduced. Therefore, the frame synchronization method for blank frame transmission provided by the invention solves the technical problem that the overall performance of the system is reduced due to high system complexity and difficulty in keeping continuous data transmission in a blank frame distinguishing mode in the existing burst transmission technology.

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...
