Test_Interrupt_guidata
MATLAB GUI控制中斷的例子方便初学者学习這裡討論MATLAB GUI中，一個元件A的Callback正在執行，如何用另一個元件B的觸發（如按鈕，或按鍵盤）來中斷程序A的執行。
(MATLAB GUI control to interrupt the examples easy for beginners to learn to discuss here the MATLAB GUI, a component A Callback is running, how to use the B trigger another component (such as buttons, or keyboard) to interrupt the execution of the program A.)

Link-a-System-Level-OFDM-Simulator
针对OFDM系统，分成链路级仿真和系统级仿真两个部分。为了降低系统级仿真的复杂度，采用链路级仿真的部分结果。(It contains mainly two parts, i.e. link-level simulator and system-level simulator.
Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation.
System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.
Link-level simulator support SISO, 1 by x MRC, 2 by 1 STBC/SFBC, 2 by 2 Alamouti, x by 1 Antenna selection, x by y antenna selection.
System-level simulator, currently support only SISO and 1 by 2 MRC.
To start with, go into the folder sys_link_simu, and excute the following commond from matlab:
sys_link_simu_func(a,b)
where a is the link ada)

KalmanFilter
this is matlab code for estimating the static linear system(system function is time variable) with Kalman Filter.
this program is written by matlab 7.0.
Here we want to estimate the below function:
this is matlab code for estimating the static linear system(system function is time variable) with Recursive Least Squre and 2 solutions for better result.
1- using the Covariance Matrix Reseting in a specefic time.
2-using the RLS with Forget Factor
this program is written by matlab 7.0.
Here we want to estimate the below function:
1-u^2+(1+tansig(0.1*(t-375)))*u^3+u^5+3*u^7
finally,there are plots for showing results.

OTHERCDMA
CDMA Simulation Using MATLAB
This program models a simple implementation of CDMA technology. It considers multiple bit data streams sent by any number of senders across a common channel. Each sender uses a unique code word, given by the Walsh set, to encode its data, send it across the channel, and then perfectly reconstruct the data at the receiver.
The simulation utilizes these simplifications:
1. The individual data streams share the same bit length.
2. The code words are determined using the Walsh set to create orthogonal code words.
3. The spreading factor M of each code word is identical.
4. All users (data streams and codes) are synchronized in time.
5. Set-up and hold times of real-world systems are ignored.
6. The channel through which the data passes is ideal.
