论文摘要
已知过滤库多载波（FBMC）的传输多样性方案是具有挑战性的。没有现有的方案考虑存在 - 安特纳纳频率偏移（IAFO），这将导致性能降解。在这封信中，提出了基于频率逆转Alamouti代码（FRAC）的结构来解决IAFO问题的新传输方案，并被证明可以固有地取消 - 安特纳纳间载流器干扰（ICI），同时保留空间多样性。此外，提出的FRAC结构适用于频率选择通道。数值结果表明，即使使用相当大的IAFOS，该提出的方案也会经历可忽略不计的位错误率（BER）降解。
Transmit diversity schemes for filter bank multicarrier (FBMC) are known to be challenging. No existing schemes have considered the presence of inter-antenna frequency offset (IAFO), which will result in performance degradation. In this letter, a new transmit scheme based on the frequency reversal Alamouti code (FRAC)-based structure to address the issue of IAFO is proposed and is proven to inherently cancel the inter-antenna inter-carrier interference (ICI) while preserving spatial diversity. Moreover, the proposed FRAC structure is applicable in frequency-selective channels. Numerical results show that the proposed scheme undergoes negligible bit error rate (BER) degradation even with considerable IAFOs.
