摘要

提出了一种混沌伪正交隐蔽(CPOC)通信系统。为了提高隐蔽通信系统的低概率检测性能，提出了混沌伪正交(CPO)信号。通过倒谱和谱相关函数(SCF)验证了CPOC系统的LPD性能。将CPOC系统的误码率(BER)性能与传统的加性高斯白噪声(AWGN)和多径信道下的差分混沌移位键控(DCSK)通信系统进行了比较。在软件定义电子(SDE)平台上进行了实验测试，验证了基于CPOC的隐蔽通信系统的可行性。

A Chaotic Pseudo Orthogonal Covert Communication System

A Chaotic Pseudo Orthogonal Covert (CPOC) communication system is proposed. The Chaotic Pseudo Orthogonal (CPO) signals is proposed to improve the Low Probability of Detection (LPD) performance in the covert communication system. The LPD performance of CPOC system is verified by the cepstrum and Spectral Correlation Function (SCF). The Bit Error Ratio (BER) performance of the proposed CPOC system is compared to the conventional Differential Chaos Shift Keying (DCSK) communication system in Additive Gaussian White Noise (AWGN) and multipath channels. The experiment test has been carried out based on a Software Defined Electronical (SDE) platform to show the feasibility of the covert communication system based on CPOC.
