摘要:

本信提出了一种新型分裂接收机设计,联合采用包络检测(ED)与相干检测(CD)。为刻画其基本性能极限,我们对所提出的 ED-CD 分裂接收机进行了高信噪比(SNR)分析,并得到了可达互信息与最优分裂比(即接收机的一项关键设计参数)的闭式近似。数值结果表明,这些高 SNR 近似在很宽的中等 SNR 取值范围内均准确,表明所得分析结果具有实用价值。我们还针对所提出的分裂接收机在何种条件下相较传统接收机具有显著性能优势给出了洞见。

英文摘要:

This letter proposes a new splitting receiver design with joint envelope detection (ED) and coherent detection (CD). To characterize its fundamental performance limit, we conduct high signal-to-noise ratio (SNR) analysis on the proposed ED-CD splitting receiver and obtain closed-form approximations of both the achievable mutual information and the optimal splitting ratio (i.e., a key design parameter of the receiver). Our numerical results show that these high SNR approximations are accurate over a wide range of moderate SNR values, signifying the usefulness of the obtained analytical results. We also provide insights on the conditions at which the proposed splitting receiver has significant performance advantages over the traditional receivers.
