ansys命令流，用于计算两端固定的三维梁动力响应(ansys command stream, used to calculate the three-dimensional beam fixed at both ends of the dynamic response)

静电场边值仿真，用差分数值计算方法，算出个点的电位(The electrostatic sidelines value simulation difference numerical calculation method to calculate a point of potential)

In Modulation schemes such as OFDM transmitter time domain signal will have higher PAPR, which leads to various distortions in the transmitter chain and degradation of system performance i.e. BER/PER. Also requires highly linear power amplifier which increases cost of the system. PAPR is ratio of peak power to average power of time domain complex baseband signal which is to be transmitted. We will discuss PAPR reduction techniques below.

基于MTALAB-simulink的汽车发动机动态仿真模型的建立。(Based on established MTALAB-simulink automotive engine dynamic simulation model.)

matlab pso toolbox 工具箱。 pso算法的matlab实现。 其中有几个经典的测试函数。(toolbox matlab pso toolbox. PSO algorithm matlab realize. Several of the classic test function.)

利用matlab里面的吹风机数据，用前300个数据进行辨识。分别采用最小二乘辨识和相关性系数法辨识。并画出图形。通过对比最小二乘法和相关函数两种方法得出来的辨识图形。可知相关函数辨识的准确度更高。(Use a hair dryer inside matlab data before using 300 data identification. Were used to identify the least squares identification and correlation coefficient method. And draw graphics. By comparing the least squares method and related functions have two ways out of the identification graphics. Shows a higher correlation function identification accuracy.)
