摘要

一种用于OFDM系统的赫米对称子载波编码(HC-OFDM)能够在单个IQ无线信道上实现双通道传输，比简单重复编码(RC-OFDM)具有更高的功率效率。我们从理论上证明了HC-OFDM系统在理想相干检测条件下的优势。但在实际应用中，双通道传输需要精确的相位补偿来分离每个通道。本文研究了HC-OFDM系统对衰落波动的鲁棒性。

Robustness against fading fluctuation in Hermite-symmetric subcarrier coding for OFDM systems

An Hermite-symmetric subcarrier coding for OFDM systems (HC-OFDM) enables dual channel transmission over individual IQ wireless channels with higher power efficiency than a simple repetition coding (RC-OFDM). We theoretically proved the advantage of the HC-OFDM systems assuming an ideal coherent detection. But, in practice, the dual channel transmission needs precise phase compensation to separate each channel. In this paper, we evaluate the robustness against fading fluctuation in the HC-OFDM systems.
