Beamforming using Leas Mean Square

matlab的启动与退出，中间变量，算术表达式和函数的调用，矩阵的运算等等。(matlab startup and exit, intermediate variables, arithmetic expressions and function calls, matrix operations, etc..)

matlab中电气化铁路上每1km长的牵引网的等效阻抗模型。(matlab in every 1km long electrified railway traction network equivalent impedance model.)

In this program we calculate the scattering field of a infinite rectangular surface. I use Physical Optic method and compare the result with exact solution.

This text provides an introduction to the numerical methods that are typically encountered (and used) in science and engineering undergraduate courses. The material is developed in tandem with MATLAB which allows rapid prototyping and testing of the methods. The package MATLAB (matrix laboratory) pro- vides an environment in which students can learn to programme and explore the structure of the numerical methods. The methods included here are of a basic nature and only rely on material which should have been explored prior to the fi rst year undergraduate stage.

这是一个接收机解映射程序，可供无线通信仿真的朋友参考(This is demapping program)

使用迭代式阈值算法来提高图像对比度。可以指定某个色阶作为阈值，所有比阈值亮的像素转换为白色；而所有比阈值暗的像素转换为黑色。 (The use of iterative threshold algorithm to enhance image contrast. You can specify a color scale as the threshold, all pixels lighter than the threshold into white and all pixels darker than the threshold value is converted to black.)

The primary objective of the QRD-M detector is to identify the candidate list. The QRD-M algorithm is a breadth-first tree search. It views all the branches it will ever consider for a given stage of the detection tree and then rejects all but the Mi best nodes at the i-th detection stage before continuing on to the next stage.
