空间调制（SM）是一种创新的和有前途的数字调制技术，它以简单的设计理念在频谱效率和能量效率之间达成了一个有吸引力的折衷。短消息具有许多优点，在满足未来无线通信需求方面显示出巨大的潜力。SM背后的关键思想是通常通过发射天线的ON/OFF状态来传达附加信息，同时通过减少射频链的数量来节省实现成本。因此，SM概念可以对不同的应用具有广泛的影响，并且可以应用于其他信号域，例如频域/时域/码域/角域或甚至跨多个域。本综述全面介绍了SM研究的最新成果和进展。具体而言，SM的基本原理，系统设计的变体，和增强进行了详细描述。此外，SM家族与其他有前途的技术，新兴的通信系统中的应用，并扩展到新的信号域的集成也进行了广泛的研究。
Spatial modulation (SM) is an innovative and promising digital modulation technology that strikes an appealing tradeoff between spectral efficiency and energy efficiency with a simple design philosophy. SM enjoys plenty of benefits and shows great potential to fulfill the requirements of future wireless communications. The key idea behind SM is to convey additional information typically through the ON/OFF states of transmit antennas and simultaneously save the implementation cost by reducing the number of radio-frequency chains. As a result, the SM concept can have widespread effects on diverse applications and can be applied in other signal domains, such as frequency/time/code/angle domain or even across multiple domains. This survey provides a comprehensive overview of the latest results and progresses in SM research. Specifically, the fundamental principles, variants of system design, and enhancements of SM are described in detail. Furthermore, the integration of the SM family with other promising techniques, applications to emerging communication systems, and extensions to new signal domains are also extensively studied.
