In this paper, we investigate the performance of Space Shift Keying (SSK) modulation on a Multiple-Input-Multiple-Output (MIMO) wireless communication system for Unmanned Aerial Vehicles (UAVs) over Rician fading channels. SSK modulation can be a key technique for energy-efficient and reliable communication scenarios for UAV applications. The first part of the performance analysis consists of theoretical derivations for the Bit Error Rate (BER) performance of UAVs' SSK communication. The second part consists of theoretical derivations for the outage probability. Error rate performance comparison between SSK modulation for UAV communication systems and conventional systems is given. Then, the proposed system's diversity order is derived and presented as a number of receive antenna $N_r$. The BER performance decrease against non-line-of-sight channel scenarios is shown via simulation results due to the line-of-sight effect on the SSK modulated system. Monte Carlo simulations validate theoretical derivation results for various transmit - receive antennas and Rician K factor values.

在本文中，我们研究了多输入多输出 (MIMO) 无线通信系统的空间移位键控 (SSK) 调制在 Rician 衰落信道上用于无人驾驶飞行器 (UAV) 的性能。SSK 调制可以成为无人机应用的节能和可靠通信场景的关键技术。性能分析的第一部分包括无人机 SSK 通信误码率 (BER) 性能的理论推导。第二部分包括中断概率的理论推导。给出了无人机通信系统和常规系统的SSK调制的误码率性能比较。然后，推导出所提出的系统的分集阶数并将其表示为多个接收天线$N_r$. 由于对 SSK 调制系统的视线效应，BER 性能相对于非视线信道情况的下降通过仿真结果显示。Monte Carlo 模拟验证了各种发射-接收天线和 Rician K因子值的理论推导结果。
