matlab下的802.11a仿真，包含channal文件，hackchina上分享(matlab simulation under the 802.11a)

Find all java objects contained within a java container or Matlab GUI handle If no output parameter is specified, then an interactive GUI window will be displayed with a tree-view of all container components, their properties and callbacks.

matlab code to add a second y-axis to a x-y plot

Integer programming Simplex code combined with TSP solver

this is matlab simulink simulation. it implies m-ary FSK with convolutional coding under AWGN channel.

说明：  TURBO译码性能AWGN信道测试（菜单式） 达到误帧限即可停止当前SNR点的测试，节省计算量(TURBO AWGN channel decoding performance test (menu type) to stop the current error frame is limited to the test SNR point, saving computation)

使用一般PI模型拟合非线性曲线，最小二乘法参数辨识，逆模型前馈(The general PI model is used to fit the nonlinear curve, the least square parameter identification, and the inverse model feedforward.)

本例演示：如何依靠图形窗 UserData 属性在递归调用中传送用户控件的图柄，保证回调动作正确执行。(demonstration of the cases : how to rely on graphics window UserData attribute in the recursive call to transfer control of the map user handles, callback action to ensure correct implementation.)
