Space shift keying (SSK) modulation performance is analyzed with simultaneous wireless information and power transfer (SWIPT) based cooperative amplify-and-forward (AF) relaying system over the Nakagami-m fading channel. SWIPT technique can remove the need for power supply at the relays in cooperative communication. In contrast, SSK is a low complex index modulation technique that eliminates inter antenna synchronization, inter-channel interference and reduces the number of radiofrequency chains. Closed-form expression for average bit error probability (ABEP) is derived using a single AF relay with selection combining (SC) at the receiver, and an Upper bound ABEP expression is derived for multiple AF relays with the direct link (DL) from source to destination. The partial relay selection (PRS) technique has been proposed with energy harvesting (EH) to reduce the hardware complexity compared to the multiple relays. Numerical and computer simulation results are presented with the discussion. The result demonstrates that EH with SSK modulation can improve the system performance.

空间移键控（SSK）调制性能进行了分析与在Nakagami-基于协同放大-转发（AF）的同时无线信息和功率传输（SWIPT）中继系统米衰落通道。SWIPT 技术可以消除协作通信中继电器供电的需要。相比之下，SSK 是一种低复杂指数调制技术，可消除天线间同步、信道间干扰并减少射频链的数量。平均误码率 (ABEP) 的闭式表达式是使用单个 AF 中继在接收器处使用选择组合 (SC) 推导出来的，并且上限 ABEP 表达式可用于多个 AF 中继与来自源的直接链路 (DL)到目的地。与多个继电器相比，部分继电器选择 (PRS) 技术与能量收集 (EH) 一起被提出，以降低硬件复杂性。数值和计算机模拟结果与讨论一起给出。
