5세대 이동통신시스템(XNUMXG)에서는 대용량·고속 통신은 물론 무선 보안도 중요하다. 이를 달성하기 위해 물리계층에서 암호화되고 채널부호화된 변조방식으로서 카오스 변조방식이 제안된다. 그러나, 기존의 카오스 변조 방식에서는 변조 차수에 따라 복호 복잡도가 기하급수적으로 증가한다. 이러한 문제를 해결하기 위해 본 연구에서는 QAM(Quadrature Amplitude Modulation)과 카오스(Chaos)를 적용하여 디코딩 복잡도를 줄이는 하이브리드 변조 방식을 제안하며, 모든 비트에 대한 암호화는 유지하면서 일부 전송 비트를 QAM에 할당하는 방식을 제안한다. 제안 방법에서는 인덱스 변조 이론을 기반으로 카오스 및 QAM 심볼을 정렬하여 저복잡도 복호 방법을 구성한다. 수치 결과는 제안한 방법이 디코딩 복잡성을 줄이면서 우수한 오류율 성능을 유지하고 무선 보안을 보장한다는 것을 보여줍니다.

Abstract: In the fifth-generation mobile communications system (5G), it is critical to ensure wireless security as well as large-capacity and high-speed communication. To achieve this, a chaos modulation method as an encrypted and channel-coded modulation method in the physical layer is proposed. However, in the conventional chaos modulation method, the decoding complexity increases exponentially with respect to the modulation order. To solve this problem, in this study, a hybrid modulation method that applies 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 is proposed. In the proposed method, a low-complexity decoding method is constructed by ordering chaos and QAM symbols based on the theory of index modulation. Numerical results show that the proposed method maintains good error-rate performance with reduced decoding complexity and ensures wireless security.
