论文摘要
本文研究了基于焊接频率选择性通道的基于偏移-QAM的滤清器多载体（FBMC-OQAM）通信的信息理论保密能力。保密能力是作为优化问题制定的，该问题具有高信噪比（SNR）制度的封闭式解决方案。考虑到FBMC-OQAM中最常见的均衡策略之一，即单tap和多tap均衡。为了进行比较，我们还考虑了通用调制的保密能力和环状前缀 - 正交频施加多路复用（CP-OFDM）调制。结果，我们发现FBMC-OQAM对于中型爆发的传输特别有竞争力。
This paper studies the information-theoretic secrecy capacity of an Offset-QAM-based filterbank multicarrier (FBMC-OQAM) communication over a wiretap frequency selective channel. The secrecy capacity is formulated as an optimization problem which has a closed-form solution in the high signal-to-noise ratio (SNR) regime. Two of the most common equalization strategies in FBMC-OQAM are considered, namely, single-tap and multi-tap equalization. For the sake of comparison, we also consider the secrecy capacity of a generic modulation and a cyclic prefix-orthogonal frequency division multiplexing (CP-OFDM) modulation. As a result, we find that FBMC-OQAM is particularly competitive for medium-to-long burst transmissions.
