Visual C++与Matlab混合编程实现语音识别(Visual C++ and Matlab programming hybrid speech recognition)

这是一个用AnCAD公司的matfor图形包写的一个小程序，实现了类似matlab封面三维图形功能，用该图形包代码量少，个人认为比matlab更能满足用VC开发的朋友。(This is a company with AnCAD graphics package matfor write a small program to achieve a similar three-dimensional graphics functions matlab cover, using the graphics package code less, think more than matlab personal use VC development to better meet friends.)

详细讲述了直接序列扩频差分锁相环的文章，包含具体的算法结构，并附有仿真结果。(A novel differentially coherent delay-locked loop(DCDLL) for accurate code tracking is proposed for direct sequence spread spectrum systems. Due to the use of the differential decoder and exactly one correlator, the proposed scheme avoids the problems of gain imbalance. The tracking error variance is derived by linear analysis. When the proposed DCDLL scheme is applied in ranging with additive white Gaussian noise (AWGN) channel, the performance of the proposed DCDLL scheme is about 1.4 dB better than that of one-correlator tau–dither loop (TDL), and near that of noncoherent DLL.)

说明：  用vb调用matlab联合编程的示例，包含com接口及带参数的传递(Joint programming with vb call matlab example, contains com interface and the transmission parameters)

读一组整数到vector对象，计算并输出每对相邻元素的和。如果读入元素个数为奇数，则提示用户最后一个元素没有求和，并输出其值。(Read a set of integers to vector objects, calculate and output, and each pair of adjacent elements. If you read an odd number of elements, the last element of the user is prompted no summation, and output its value.)

二维的TM波打到一个方形的金属柱上，边界条件为PML(TM wave hit a two-dimensional square metal column, PML boundary conditions)

使用C语言写的捷联惯导解算程序，四子样旋转矢量(Using C language to write the strapdown inertial navigation program, four sample rotation vector)

Hide That Window!，可对指定窗口进行隐藏、修改透明度、修改标题、查看窗口类等(Hide That Window !, available for the specified window is hidden, change transparency, modify the title, the viewing window etc.)

这是用itpp库编写的卷积码的解码程序。由于用C++库和Intel的MKL库，所以速度飞快。同样的仿真点数， Matlab2012下用了15分半钟，而这个程序仿真只用了半分钟，相当于是matlab速度的30多倍。(This is itpp prepared for the convolutional code decoding process. Because with C++ libraries and Intel' s MKL library, so fast. The same simulation points under Matlab2012 spent 15 and a half minutes, and this program simulation with only half a minute, the equivalent of 30 times the speed of matlab.)

This project seeks to implement H.264 (the standard x264 is based on) to run on CUDA. Specifically we attempt to write the motion estimation module in CUDA. Motion estimation is currently the most computationally intensive portion of the H.264 encoding process. Previous attempts to parallelize this algorithm in CUDA showed sizeable speedups but sacrificed quality by ignoring the motion vector prediction (MVp). We demonstrate the viability of a hierarchical (pyramid) motion estimation algorithm in CUDA. This solution addresses the MVp problem while still taking advantage of the CUDA framework.
