摘要

OFDM-IM技术可以在不影响带宽扩展的情况下，利用索引子载波传输额外的比特，从而提高系统吞吐量。在航空卫星通信中部署OFDM-IM可以解决航空通信系统的需求和增长。但面临的挑战是基于卫星OFDM-IM和l波段传统系统的共存。研究了地面与卫星OFDM-IM系统频谱共享对系统性能的影响。推导了基于不同场景的系统中断概率表达式。结果显示了干扰的影响，并会显著降低系统的性能。导出的公式有助于预测干扰效应和进一步的干扰分析。

Outage Performance for Aeronautical Satellite OFDM-IM System

OFDM-IM technique can increase system throughput by transmitting extra bits using index sub-carriers without jeopardizing the bandwidth expansion. The demands and growth in aeronautical communications systems can be solved by deploying OFDM-IM for aeronautical satellite communications. But the challenge is the coexistence between the proposed satellite OFDM-IM based and L-Band legacy systems. This paper investigates the effect of system performance due to spectrum sharing between the terrestrial and satellite OFDM-IM systems. The system outage probability expressions based on different scenarios were derived. The results demonstrate the interference impact and can significantly degrade the system performance. The derived formulas help predict interference effects and further interference analysis.
