Title:
DIFFERENTIAL CHAOS SHIFT KEYING COMMUNICATION METHOD BASED ON HYBRID SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/107316
Kind Code:
A1
Abstract:
Disclosed is a differential chaos shift keying communication method based on a hybrid system, comprising the steps of: step 1, setting communication system parameters; step 2, preparing binary information to be sent: presetting binary information; S3, generating a chaotic signal u1; step 4, preparing a signal to be transmitted u3; step 5, performing chaotic matched filtering on a received signal; and step 6, determining the polarity of a code element: respectively performing related operations on two segments of signals, to obtain a recovered signal by decoding. The method of the present invention effectively simplifies a system structure on the basis of ensuring the reliability of a communication system, and is easy for implementation and integration of a microprocessor; the method enables normal operation at a low signal-to-noise ratio, thereby improving the reliability of the communication system; and the method enables a transmitted signal to adapt to a channel bandwidth, and has strong resistance to narrow-band interference.
