본 논문에서는 공간 자유도(DoF)를 활용하고 공간 변조(SM)의 단순한 설계 이점을 활용하여 효율적인 다중 구성 선택 메커니즘을 개발하는 데 중점을 둡니다. 특히, SM 기술과 그 변형은 다음과 같은 중요한 과제에 직면해 있습니다.i) 더 높은 레벨의 QAM 성좌에 대한 시스템 성능 개선의 어려움 및 성능 저하, 및 (ii) 특히 증가하는 시스템 크기와 진폭-위상 변조(APM) 성좌 크기에 대한 프리코더 설계의 막대한 복잡성 비용. 이러한 상황을 고려하여 먼저 두 개의 독립적인 변조 영역, 즉 원래의 신호 및 공간 성상을 조사합니다. 아날로그 편이 가중치와 가상 공간 서명 기술을 활용하여 스펙트럼 효율성과 비용 효율성, 시스템 BER(비트 오류율) 성능 간의 우수한 균형을 보장할 수 있는 SSM(Signature Spatial Modulation) 개념을 도입합니다. . 게다가, 우리는 도입된 제약 없는 라그랑주 이중 함수 최소화 문제를 해결하여 SSM을 위한 아날로그 빔포밍을 개발합니다. 수치 결과는 당사가 개발한 SSM용 아날로그 빔포밍이 가져온 성능 향상을 나타냅니다.

Abstract: In this paper, we focus on developing efficient multi-configuration selection mechanisms by exploiting the spatial degrees of freedom (DoF), and leveraging the simple design benefits of spatial modulation (SM). Notably, the SM technique, as well as its variants, faces the following critical challenges: (i) the performance degradation and difficulty in improving the system performance for higher-level QAM constellations, and (ii) the vast complexity cost in precoder designs particularly for the increasing system dimension and amplitude-phase modulation (APM) constellation dimension. Given this situation, we first investigate two independent modulation domains, i.e., the original signal- and spatial-constellations. By exploiting the analog shift weighting and the virtual spatial signature technologies, we introduce the signature spatial modulation (SSM) concept, which is capable of guaranteing superior trade-offs among spectral- and cost-efficiencies, and system bit error rate (BER) performance. Besides, we develop an analog beamforming for SSM by solving the introduced unconstrained Lagrange dual function minimization problem. Numerical results manifest the performance gain brought by our developed analog beamforming for SSM.
