| Abstract(in English) | Chaos multiple-input multiple-output (C-MIMO) scheme is a transmission scheme having both physical layer security and channel coding gain, and a turbo-coded transmission is also available by introducing a log-likelihood ratio (LLR), which enables larger coding gain in C-MIMO. However, the convergence characteristic of turbo-coded C-MIMO is not analyzed yet. Here, it is well-known that the convergence characteristics of turbo decoding can be analyzed by EXIT chart. In the EXIT chart, the input-output mutual information of two element decoders is plotted in a same plane in pairs, and the increase of mutual information obtained by iterative decoding can be confirmed on the trajectory of two EXIT curves. Therefore, in this paper, we analyze the performance of turbo-coded C-MIMO by using EXIT chart. As a result, it is found that the output mutual information continuously increases in C-MIMO because of rate-1 channel coding property, and that C-MIMO is suitable for iterative decoding. In addition, it is shown that the bit error rate (BER) characteristics of turbo-coded C-MIMO basically coincide the results of EXIT chart analysis. |
