this matlab code calculate the input impedance and current distribution of microstrip patch antenna with coax excitation in different place.

可以产生PN码序列，可用于直扩通信等需要PN序列的地方。(Can generate PN code sequence, can be used for DSSS communications needs of the local PN sequence.)

PID参数的整定就是合理的选择PID三参数。从系统的稳定性、响应速度，超调量和稳态精度等各方面考虑问题，三参数的作用如下：(PID parameter setting is the reasonable choice of three parameters of PID. From the system stability and response speed, overshoot and steady state accuracy and so on various aspects to consider problem, the role of the three parameters are as follows:)

系统辨识的MATLAB程序，有增广最小二乘辨识，广义最小二乘辨识(MATLAB system identification procedures, extended least squares identification, generalized least squares identification)

Run Application =============== Windows: Doubleclick the BicAT_v2.2.jar file Linux: type ./run_linux to start the application. Solaris: type ./run_solaris to start the application. possible problems: ================== Make sure the environment variables are properly set! CLASSPATH (should be ok) LD_LIBRARY_PATH = ./lib/linux ./lib/solaris Sample Data Files ================= dataSample_1.txt - use offsets (1,1) (data are already logarithmized) dataSample_2.txt - use offsets (1,1) (Run Application =============== Windows: Doubleclick the BicAT_v2.2.jar file Linux: type ./run_linux to start the application.
