在最近的无线通信系统中，主要在诸如口令或密码处理的上层技术中确保安全性。然而，安全性不需要仅限于上层，增加物理层安全性也将产生一个更健壮的系统。因此，在本文中，我们利用混沌通信，提出了一种混沌多输入多输出(MIMO)传输方案，实现了物理层的安全性和额外的信道编码增益。在每个MIMO天线处将一个混沌调制符号与待发送的数据相乘以利用MIMO天线分集，在接收端通过最大似然译码(MLD)完成联合MIMO检测和混沌译码。传统的混沌调制存在误码率(BER)性能下降的问题，而该方案的编码增益是通过MIMO中的混沌调制获得的。我们通过一个实例对该方案的性能进行了评估
SUMMARY In recent wireless communication systems, security is ensured mainly in the upper-layer techniques such as a password or a cryptography processing. However, security needs not be restricted to the upperlayer and the addition of physical-layer security also would yield a much more robust system. Therefore, in this paper, we exploit chaos communication and propose a chaos multiple-input multiple-output (MIMO) transmission scheme which achieves physical-layer security and additional channelcoding gain. A chaotic modulation symbol is multiplied to the data to be transmitted at each MIMO antenna to exploit the MIMO antenna diversity, and at the receiver, the joint MIMO detection and chaos decoding is done by maximum likelihood decoding (MLD). The conventional chaos modulation suffers from bit error rate (BER) performance degradation, while the coding gain is obtained in the proposed scheme by the chaos modulation in MIMO. We evaluate the performances of the proposed scheme by an
