| Abstract(in English) | In the fifth generation mobile communications system (5G), it is important to ensure wireless security as well as to realize large capacity and high speed communication. To realize it, we have proposed a chaos modulation as an encrypted and channel coded modulation method in mobile communication systems. However, in the conventional chaos modulation method, the decoding complexity exponentially increases with respect to the modulation order. To solve this problem, in this paper, we propose a hybrid modulation method applying quadrature amplitude modulation (QAM) and chaos to reduce the amount of decoding complexity, in which some transmission bits are allocated to QAM while maintaining the encryption for all bits. Numerical results show that the proposed system keeps good error rate performance with reduced decoding complexity and ensures the wireless security. |
