标题： Asynchronous Peak Detection for Demodulation in Molecular Communication

摘要： 分子通信需要低复杂度的符号检测算法来处理这些信道中固有的许多不确定性来源。 本文提出了一种高性能异步峰值检测算法的两种变体，该算法的接收器进行独立观测。 第一种变体具有低复杂度，并在采样间隔内测量最大的观测值。 第二种变体添加了决策反馈以减轻符号间干扰。 尽管该算法不需要发射机和接收机之间的同步，但结果表明，使用第一种变体进行逐符号检测的比特错误性能优于使用预先选择采样时间的单个样本。 第二种变体被证明其性能与能量检测器相当。 该算法的两种变体在抗定时偏移方面比现有检测器更具鲁棒性。 显示英文摘要

摘要： Molecular communication requires low-complexity symbol detection algorithms to deal with the many sources of uncertainty that are inherent in these channels. This paper proposes two variants of a high-performance asynchronous peak detection algorithm for a receiver that makes independent observations. The first variant has low complexity and measures the largest observation within a sampling interval. The second variant adds decision feedback to mitigate inter-symbol interference. Although the algorithm does not require synchronization between the transmitter and receiver, results demonstrate that the bit error performance of symbol-by-symbol detection using the first variant is better than using a single sample whose sampling time is chosen a priori. The second variant is shown to have performance comparable to that of an energy detector. Both variants of the algorithm demonstrate better resilience to timing offsets than that of existing detectors.
