说明：  SLM算法降低OFDM通信系统中的PAPR，使用matlab进行仿真(SLM algorithm reduces PAPR in OFDM communication system, and matlab is used for simulation)

本文基于对工业机器人运动学系统的分析与探讨，从运动学方程的建立、运动学方程的求解、运动空间的插值算法、机器人轨迹规划等几个方面推求新的算法，并利用这些算法实现对于工业机器人运动学系统的三维图形仿真。 (Analysis and Discussion of the industrial robot kinematics system from several aspects of the establishment of the kinematic equations, the kinematic equations, the motion space of the interpolation algorithm, the robot trajectory planning Deriving a new algorithm, and use of these algorithms to achieve three-dimensional graphic simulation system for industrial robot kinematics.)

感觉这份代码中最有价值的应该是水声信道的建模，该源码来自美国 Parastoo Qarabaqi, Northeastern University, 2013其次其提供了基于l1范数下PCA处理算法，来对经由水声信道的信号进行处理给出误码率图，启动比较程序需要先使用信道生成函数对信号进行生成。(The most valuable part of this code is the modeling of underwater acoustic channel. Secondly, it provides a PCA processing algorithm based on L1 norm to process the signals passing through the underwater acoustic channel and gives a bit error rate chart. To start the comparison program, the channel generating function is needed to generate the signals first.)

说明：  这是最新的卫星通信基础理论的Matlab仿真实现，pcma以及信号衰减和延迟的仿真。尽管不是我本人原创，但比较都经典。文件为*.m格式 (This is the latest in satellite communications theoretical basis Matlab Simulation, pcma and signal attenuation and delay in the simulation. Although it was not my original, but more are classics. M*. document format)
