matrix theory：Mathematically rigorous introduction covers vector and matrix norms, the condition-number of a matrix, positive and irreducible matrices, much more.(matrix theory)

由信道信号的复数值解调对应的二进制序列由信道信号的复数值找出对应的二进制序列。方法如下：由信道值， ％％求出该值与星座图中所有点的距离，找出距离最小的点，该点对应的 ％％二进制序列及为该信道对应的解调结果。 (Channel signal by the complex demodulation value corresponding to the binary sequence by the complex channel signals to identify the corresponding binary numerical sequence. As follows: by the channel value, the value obtained with the constellation diagram of all points of distance, find the smallest distance between points, the points of the corresponding binary sequence and the corresponding channel demodulation results.)

Backpropagation, an abbreviation for backward propagation of errors , is a common method of training artificial neural networks used in conjunction with an optimization method such as gradient descent. The method calculates the gradient of a loss function with respects to all the weights in the network.

说明：  该文件基于Matlab的GUI界面设计了6自由度串联机器人的运动学、动力学和轨迹规划的算法，用户可以计算PUMA560型的机器人的正逆运动学，正逆动力学和指定的轨迹规划，同时可以动画显示机器人点对点的运动路线。该程序可进行二次开发，用户可根据机器人模型的不同修改参数，针对自身模型进行运动学、动力学和轨迹规划的计算与仿真。(Based on the GUI interface of matlab, this paper designs an algorithm for kinematics, dynamics and trajectory planning of 6-DOF serial robot. Users can calculate the forward and inverse kinematics, forward and inverse dynamics and specified trajectory planning of PUMA560 robot. At the same time, they can animate the point-to-point motion path of the robot. The program can be redeveloped. Users can modify parameters according to different robot models, and calculate and simulate kinematics, dynamics and trajectory planning of their own models.)
