论文摘要
这封信提出了一种新的分裂接收器设计，并具有关节包络检测（ED）和相干检测（CD）。为了表征其基本性能极限，我们对拟议的ED-CD分裂接收器进行了高信噪比（SNR）分析，并获得可实现的共同信息和最佳分裂比（即接收器的关键设计参数）的闭合形式近似值。我们的数值结果表明，这些高SNR近似值在广泛的中等SNR值中是准确的，这表示所获得的分析结果的有用性。我们还提供有关拟议的分裂接收器与传统接收器具有显着性能优势的条件的见解。
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.
