A proposal of chaos MIMO for secure communications at physical layer
Eiji Okamoto (Nagoya Inst. of Tech.) RCS2010-93
Abstract (in Japanese) (See Japanese page) 
(in English) A secure communication is achieved by upper layer applications such as common key cryptosystem or public key cryptosystem in the current transmission systems. However, the security is never exclusive and the multiplexing of security schemes is highly effective, so the secure transmission scheme at physical layer is also important. One of the typical physical-layer schemes is a chaos transmission, which produces a secure, safe, wired or wireless communication. However, the main drawback of the chaos scheme is the error-rate performance degradation. We proposed a chaotic convolutional code which improved the performance in the tradeoff with decoding complexity increase. Here, in this paper, we focus on the diversity property of multiple-input multiple output (MIMO) and propose a chaos MIMO transmission scheme to achieve the secure at physical-layer, low error-rate, and low complexity transmission. The joint MIMO detection and chaos decoding is done by maximum likelihood decoding (MLD) at the receiver. We will evaluate the performance of proposed scheme by computer simulations.
