Summary:
In wireless transmission, an additional security or simplification of the conventional upper layer security protocols can be provided by ensuring physical layer security. To achieve not only this physical layer security but also channel coding gain, we have proposed a chaos multiple-input multiple-output (MIMO) transmission scheme in which chaos signals correlated by transmit bits are multiplied to each transmit symbols of MIMO. However, to make the chaos MIMO more effective, the error rate performance needs to be improved. In MIMO transmission techniques, a space-time block code (STBC) is proposed to obtain a space diversity gain and to improve the error rate performance, and is widely used. Therefore, in this study, we propose a chaos MIMO-STBC scheme applying the STBC into chaos MIMO scheme, and show that the improved error rate performance with a physical layer security is obtained.
