本文利用Matlab／Simulink软件，以无线电调幅广播发射与超外差接收系统为例，对“通信电子电路”课程中重要的通信系统单元电路进行了仿真和分析，给出了仿真模型和较为详细的各点仿真波形，并结合实际给出了多路系统的仿真结果。将该Matlab仿真引入课程教学。可以使学生在学好课程的同时，了解和掌握通信系统建模与仿真的方法。(In this paper, the use of Matlab/Simulink software to the radio superheterodyne AM radio receiver system with the launch as an example, the " communication electronic circuits" course an important element of communication system circuit simulation and analysis, the simulation model and the more detailed Simulation waveform points, combined with the actual multi-channel system is given the simulation results. Matlab simulation of the introduction of the teaching. Will enable students to study courses at the same time, understanding and knowledge of modeling and simulation of communication systems approach.)

利用顺序消元法和列主元消元法，分别解线性方程组。(Using the order of elimination method and main-element elimination method for solving linear equations, respectively.)

Unscented Kalman Filter (UKF) exemplified on FitzHugh-Nagumo neuron dynamics. Voltage observed, currents and inputs estimated. FitzHughNagumo.m is the main program which calls the other programs. If you use these programs for your publications etc., please refer to H.U. Voss, J. Timmer & J. Kurths, Nonlinear dynamical system identification from uncertain and indirect measurements, Int. J. Bifurcation and Chaos 14, 1905-1933 (2004). I will be happy to email this paper, which contains a tutorial about estimation of hidden states and unscented Kalman filtering. For commercial use and questions, please contact me.
