Space-time chaos double coupling drive system and code error detecting and handling method

Abstract

Disclosed is a spatiotemporal chaos double-coupling drive system which improves the capability of resisting the error drive signal of the spatiotemporal chaos system. The technical proposal is that the spatiotemporal chaos double-coupling drive system comprises a transmitter spatiotemporal chaos drive system and a receiver spatiotemporal chaos drive system; wherein, the transmitter chaos drive system comprises two chaos systems which are in linear coupling with each other; the system functions are respectively y=f1(x) and y=f2(x); The system functions output the sequences {x1(n)} and {x2(n)}; the outputted sequence {x2(n)} of the second chaos system is used as the drive sequence of the transmitter spatiotemporal chaos system; the receiver spatiotemporal chaos drive system comprises two chaos systems which are separated from each other; the system functions of the two chaos systems are y=f1(x) and y=f2(x) which are the same as the system functions of the transmitter chaos system; the receiver chaos systems are respectively coupled with the sequences {x`1(n)} and {x`2(n)} which are transmitted through the channel to output the sequences {x``1(n)} and {x``2(n)}. The spatiotemporal chaos double-coupling drive system also provides the spatiotemporal chaos double-coupling drive system with error code detection and the processing method.

Description

technical field [0001] The invention belongs to the field of space-time chaotic technology coupled drive system, in particular to a space-time chaotic system double-coupled drive system and a code error detection and processing method thereof. Background technique [0002] With the rapid growth of the amount of information and the increasingly complex way of information dissemination, the traditional linear method can no longer meet the development requirements of the actual communication system, so nonlinear mathematical tools have been used more and more in recent years. With the gradual deepening of researchers' understanding of the nonlinear field, the study of space-time chaotic systems has received more and more attention, and has also been widely used. The initial value sensitivity and inherent randomness of the chaotic system make the sequence generated by the chaotic system have good pseudo-random properties and high secrecy, so the chaotic system has a strong role ...

Problems solved by technology

Due to the error diffusion characteristics of the space-time chaotic system, if a bit error occurs in the transmission process of the driving sequence, it will cause serious out-of-synchronization phenomenon at the receiving end, which will affect the performance of the system and even cause the system to fail to work normally.

[0004] From the above analysis, it can be seen that when the spatio-temporal chaotic system is used in actual scenarios, the influence of bit errors in the driving sequence cannot be ignored
