序言 在无线局域网中,主要的性能除了吞吐量之外,另外一项比较受人关注的就是覆盖范围,而为了计算Wi-Fi的覆盖范围,我们首先要梳理其链路模型。本文我们基于基本的自由空间传输损耗模型(Free-space path loss),对802.11中的链路模型进行分析。 注:在该文之后,我们会基于在理解链路模型的基础上,继续讨论如何计算无线的...

This paper presents a study on path planning for 6-DOF free-floating space robotic manipulators using Deep Deterministic Policy Gradient-based Reinforcement Learning. The focus is the development of a novel reward function tailored to address critical requirements for efficient and effective manipulation ...
