Abstract
Spatial modulation (SM) is a contemporary and promising digital modulation technique that offers an intriguing balance between spectral efficiency and energy efficiency, accompanied by a convenient graphical approach. SM brings numerous advantages and exhibits remarkable potential in meeting the demands of future wireless communications. The fundamental concept behind SM is to transmit more information by utilizing the ONOFF states of transmit antennas, while simultaneously reducing implementation costs by minimizing the number of radio frequency chains. Consequently, the concept of SM has significant implications across various domains, including frequency, time, code, angle, and even multiple domains. This survey provides a comprehensive overview of the latest findings and advancements in SM research. It delves into the core principles, system design variations, and enhancements of SM in meticulous detail. Additionally, the survey extensively explores the integration of the SM family with other promising techniques, its applications in emerging communication systems, and its extensions to novel signal domains
