摘要

本文介绍了低轨卫星辅助广义空间移位键控（LEO- gssk）方案，它是一种具有令人满意的频谱效率和误码率性能的折衷无线方案。采用先进的天线组合选择策略，进一步降低复杂性，提高误码率。在保持可接受误码率的前提下，设计了低复杂度的检测器。该检测器还降低了复杂性并减轻了不完美的CSI估计的副作用。本文介绍了LEO-GSSK方案的分析性能，并在仿真结果中给出了一些有趣的见解和结论。此外，为了接近实际的无线环境，在仿真结果中考虑了不完善的CSI估计。理论分析和仿真结果表明，采用新颖的天线组合选择和探测器设计的LEO-GSSK方案优于传统方案，为满足卫星通信的高数据速率和可靠连接需求提供了一种有希望的解决方案。

LEO Satellite-Assisted GSSK With Optimized Antenna Combination Selections and Detector

This letter introduces the LEO satellite-assisted generalized space shift keying (LEO-GSSK) scheme, as a trade-off wireless scheme with satisfactory spectral efficiency and bit error rate (BER) performance. We adopt advanced antenna combination selection strategies to further decrease complexity and enhance BER performance. Moreover, a low-complexity detector is designed in this investigated scheme while maintaining the acceptable BER. This detector also reduces complexity and mitigates the side effects of imperfect CSI estimation. The analytical performance of the LEO-GSSK scheme is presented in this letter, along with some interesting insights and conclusions given in simulation results. Besides, to approach practical wireless environment, the imperfect CSI estimation is considered in simulation results. The theoretical analysis and simulation results indicate that the LEO-GSSK scheme with novel antenna combination selection and detector designs, outperforms traditional schemes, offering a promising solution to meet the high data rate and reliable connectivity demands of satellite communications.
