Chaos Communication DCSK Using TENT Chaotic Signal Modulation

In modern communication systems, Chaos Communication DCSK represents a communication technology utilizing TENT chaotic signals for modulation. This system's modulation and demodulation implementation involves generating chaotic reference signals through TENT map iterations and embedding information bits via differential chaotic shift keying. The transmission process typically employs a two-phase structure: the first half transmits the chaotic reference signal while the second half carries the modulated information-bearing signal. At the receiver end, correlation detection algorithms compare the two signal segments to recover transmitted data, ensuring both security and reliability through chaotic signals' inherent unpredictability. The high unpredictability of chaotic signals makes this technology widely applicable in military and commercial domains. Furthermore, DCSK enhances communication robustness and anti-interference capability by enabling data transmission across multiple channels. From an implementation perspective, key functions include chaotic sequence generation using TENT map equations xₙ₊₁ = μ·min(xₙ,1-xₙ), signal framing for reference and data transmission phases, and correlation-based detection algorithms for demodulation. Overall, Chaos Communication DCSK demonstrates broad application potential and significant value in modern communication systems.
