Self-synchronizing scrambling and descrambling communication method and device

Abstract

The invention relates to a self-synchronizing scrambling and descrambling communication method and device. The method comprises: a sending end combining data to be transmitted into a data frame according to the format of a frame header and original data; the sending end performing exclusive-OR scrambling on the data frame by using a linear-feedback polynomial and sending the data frame to a receiving end; the receiving end recovering the synchronous clock based on the received data frame; the receiving end performing exclusive-OR descrambling on the received data frame by using the inverse polynomial of the linear-feedback polynomial; and the receiving end analyzing the original data from the descrambled data frame based on the synchronous clock according to the frame header. According tothe embodiment of the invention, on the premise of ensuring data security and stability, self-synchronizing scrambling and descrambling lightweight transmission is realized. The method is particularlyapplied to a small point-to-point communication system, the system cost is reduced, and the development efficiency is improved.

Description

Technical field [0001] The invention relates to the field of communication technology. The present invention further relates to a method and device for self-synchronization and descrambling communication. Background technique [0002] With the development of FPGA (Field Programmable Gate Array) technology, more and more small communication systems are implemented by FPGA. These small systems are often used to transmit small amounts of data such as control status indication information and village-level telephone voice information. These communication systems need to adopt more complex implementation methods, so they need to invest more financial resources (such as purchasing IP cores, intellectual property cores) and longer development time, resulting in increased product costs. For example, the existing technical solutions generally adopt the data frame structure plus 8b / 10b line coding to realize the communication, which requires the purchase of 8b / 10b encoding and decoding I...

These communication systems need to adopt more complex implementation methods, so they need to invest more financial resources (such as purchasing IP core, intellectual property core) and longer development time, resulting in an increase in product costs

For example, the existing technical solutions generally adopt the data frame structure plus 8b / 10b line coding to realize the communication, which requires the purchase of 8b / 10b coding and decoding IP core, and also controls the comma (comma, data A commonly used delimiter in transmission) is realized, which increases the cost of the product, especially for small and lightweight communication systems, which has a great negative impact on system cost and development efficiency
