检测发射器是否正在与接收器主动通信是分子通信中的一个基本问题。球形接收器不仅可以测量吸收分子的数量和到达时间，还可以测量它们在接收器表面的吸收位置。这些位置包含方向性特征，而这些特征在仅计数检测中会丢失。在本信中，我们开发了一种基于接收器表面命中密度的勒让德多项式展开的分子信号检测器，并将其扩展为基于勒让德的维特比序列检测器。通过利用分子到达的表面级方向性特征，所提出的检测器提供了几何感知、高效且性能优于仅计数检测的替代方案。
英文摘要
Detecting whether a transmitter is actively communicating with a receiver is a fundamental problem in molecular communications. A spherical receiver may measure not only the number and arrival times of absorbed molecules, but also their absorption locations on the receiver surface. These locations contain a directional signature that is lost in count-only detection. In this letter, we develop a molecular signal detector based on a Legendre polynomial expansion of the receiver-surface hit density and extend it to a Legendre-based Viterbi sequence detector. By exploiting the surface-level directional signature of molecular arrivals, the proposed detectors provide geometry-aware, efficient, and better-performing alternatives to count-only detection.
