16QAM基带 在 AWGN 信道下的调制解调仿真程序 无信道编码(16QAM AWGN)

这是wimax标准的ldpc码的译码程序 编码程序在文件夹ldpc_minioffset/matlab中，为matlab的源程序(This is the standard ldpc wimax decoding program code program in the folder ldpc_minioffset/matlab in the source code for the matlab)

心音信号进行小波消噪，效果较好，可直接使用(Heart sound signal wavelet denoising, better, can be used directly)

针对智能车路径规划的问题，采用人工势场法进行智能车的路径规划，进而为智能车提供一条安全无碰的较优路径。本程序基于源程序进行了改动，松弛了迭代终止条件，避免智能车绕过目标无限探测下去。(Smart car for path planning problem, the use of artificial potential field of intelligent vehicle route planning, thereby providing a safe path for the optimum touch smart car. The program is based on the source code made changes, relaxation iteration termination conditions, avoid detection infinitely intelligent car rounded the target down.)

640*480 256 色 .BMP 文件显示程序，可以浏览、同时显示 4 幅图象，也可以 在屏幕上开 一个窗口显示 .BMP 图象，并可以使用上下左右箭头键、PageUp/PageDown、Ctrl+Left、Ctr l+Right键浏览整幅图象，在S3、ATI等VGA卡上 调试通过(640* 480256 color. BMP file display program can browse, also showed four images on the screen can also open a window on the show. BMP images and can be used above and below the arrow keys, and Page/Prompt, Ctrl Left, Right keys Ctr l View the entire images in S3, ATI VGA cards such as debugging through)

hydroterman two area simulation

输入参数接非线性薛定谔方程，没有标准化过的U，需要U0(Input parameters then the nonlinear Schrö dinger equation, there is no standardized over the U, needs U0)

关于QPSK星座图的部分程序，本人搜索到的，感觉挺好的，大家可以看看，参考一下。(QPSK constellation diagram on the part of the process, I searched, feeling quite good, we can see that reference.)

卷积码是一种有记忆的编码，在任意给定的时间单元处，编码器的n个输出不仅与此时间单元的k个输入有关，而且也与前m个输入有关。卷积码通常表示为：（n,k,m） 本次仿真采用（2，1，3）卷积码。 (convolutional code is a kind of code memory, in any given unit of time, the encoder output n this time not only with the elements of the k input, but also with the input m. Convolutional codes are usually stated as : (n, k, m), the simulation used (2,1,3) convolutional code.)
