Summary:
For the achievement of smart community which comprehensively controls social infrastructures, it is expected that wireless multihop networks are utilized. In the wireless multihop transmission, personal data are forwarded by the third person so that the wireless security is indispensable. In current wireless systems, the security is ensured by encryption at the upper layers. However, it tends to need a complex protocol or processing which is not suitable for the multihop protocol with a simple manner. To solve it, we have proposed a chaos multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) scheme having physical-layer encryption and channel-coding abilities. However, the multiuser transmission which is essential for efficient multihop network has not been considered yet. Therefore, in this paper, we propose a multiuser (MU) chaos MIMO-OFDM scheme which achieves the physical-layer security and channel-coding gain in MU-MIMO transmission. The improved performances are shown through computer simulations.
