Outline of Final Research Achievements

We have proposed a chaos multiple-input multiple-output (MIMO) transmission scheme that achieves both channel coding gain and physical layer security. In this research, we improved chaos MIMO scheme. To reduce the decoding complexity, we applied M-algorithm into chaos MIMO. In addition, we compose a turbo coding scheme in chaos MIMO with outer channel codes such as low-density parity check (LDPC) code and realize a large channel coding gain. In regard to security, we analyzed the encryption ability of chaos MIMO and showed that chaos MIMO had sufficient security ability.
