我们提出了一种新的选择性多载波索引键控技术，它可以机会性地同时调制一小部分子载波及其索引。特别是，我们研究了在错误传播敏感和设备到设备(D2D)安全通信的两种情况下的性能提升。在性能评估方面，重点分析了在存在不完全检测和完全检测两种情况下的误码传播概率，给出了检测误码概率的精确表达式和上界表达式。利用矩母函数将闭合形式的平均EPP结果推广到各种衰落分布，我们的数值结果清楚地表明所提出的方法对于可靠和节能的D2D应用是可取的。
We propose a new selective multi-carrier index keying in orthogonal frequency division multiplexing (OFDM) systems that opportunistically modulate both a small subset of sub-carriers and their indices. Particularly, we investigate the performance enhancement in two cases of error propagation sensitive and compromised device-to-device (D2D) communications. For the performance evaluation, we focus on analyzing the error propagation probability (EPP) introducing the exact and upper bound expressions on the detection error probability, in the presence of both imperfect and perfect detection of active multi-carrier indices. The average EPP results in closed-form are generalized for various fading distribution using the moment generating function, and our numerical results clearly show that the proposed approach is desirable for reliable and energy-efficient D2D applications.
