| Abstract(in English) | In this paper, we propose a use of the modulation as a personal identification in wireless communications. In multi-hop transmissions or picocell and femtocell, a relatively large received signal power, i.e., large signal to noise power ratio (SNR), can be obtained because of the short-range wireless transmission and the dominant factor for high-quality transmission becomes a co-channel interference, i.e., signal to interference and noise power ratio (SINR). If the co-channel interference can be avoided, the large SNR can be acquired. Meanwhile, a chaos communication which provides a physical-layer security suffers from the decrease of minimum squared Euclidean distance to a half of BPSK as the cost of the physical-layer security. However, it will be an effective modulation scheme in the short-range transmission. Utilizing the chaos modulation, we have proposed a chaos multiple-input multiple-output (C-MIMO) transmission scheme which is a chaotic channel coding scheme between multiple transmit antennas of MIMO multiplexing, achieving a high-capacity and secure wireless communication. In this paper, we consider the chaos configuration of C-MIMO and investigate the coding characteristics including bit error rate performances. Since the squared Euclidean distance property changes according to the configuration of chaos vector and chaos composition, we conduct a heuristic search and clarify a good configuration. Then, we describe a concept of personal modulation using this chaos transmission. |
