调制识别是非协作通信中的关键技术之一，在电子对抗、软件无线电等领域 应用十分广泛。该过程介于信号检测与解调之间，由于对传输信号没有过多的先 验信息以及在接收端有很多未知的参数，例如：信号功率，载波频率和相位偏移， 时间信息等，导致对调制方式的盲识别是一项很困难的任务。此外，实际中存在 多径衰落、频率选择性和时变信道等问题，使得这项任务变得更具有挑战性。 (The modulation recognition is one of the key technologies of the non-cooperative communication, such as electronic countermeasures and software defination radio, therefore it is such a significant discipline and orientation in the research of communication field. Obviously, without enough knowledge in transmitter and verified parameters about receivers, for example signal power, carrier frequency and phase offsets and so force, it is hard to get the modulation of blind identification. What is more, for the sake of the multipath fading, frequency-selective and time-varying channels in the real scenarios the task is even harder. )

说明：  在研究自主运动规划问题之前，首先需建立相对较为完整的自主运动规划体系，再由该体系作为指导，对自主运动规划的各项具体问题进行深入研究。本节将根据自主机器人的思维方式、运动形式、任务行为等特点，建立与之相适应的自主运动规划体系。并按照机器人的数量与规模，将自主运动规划分为单个机器人的运动规划与多机器人协同运动规划两类规划体系。(Before studying the problem of autonomous motion planning, it is necessary to establish a relatively complete system of autonomous motion planning, and then conduct in-depth study on the specific issues of autonomous motion planning under the guidance of this system. In this section, an adaptive autonomous motion planning system will be established according to the characteristics of autonomous robot's thinking mode, motion form and task behavior. According to the number and scale of robots, the autonomous motion planning system is divided into two types: single robot motion planning and multi robot collaborative motion planning.)
