BER with Viterbi decoder

说明：  ofdm仿真的入门代码，对初学者来说很有用的(entry-OFDM simulation code, for example very useful for beginners)

这个方法有两个好处。 （ a ）虽然只是一个半径差逼近，很容易找到最高在一个小蓄电池，因为通过降低 隐平滑做的蓄电池。（ b ）在同一时间处理时间搜索减少 (Pattern Recognition and Image Procesing Group. The size of the accumulator is varied as hierarchical voting is performed. This has two advantages. [a] While the radius is only a poor approximation, it is easier to find the maximum in a small accumulator and because by means of the downsampling implicit smoothing is done to the accumulator. [b] At the same time processing time for the search is reduced.)

介绍如何在VC中调用matcom编译后的函数； 如在调试过程中遇到困难请详见VC知识库文章 - 浅析VC与Matlab联合编程二.mht” 文件(Introduction How to call Matcom compiled function in VC )

对多径信道的仿真 输入码元,是一行矩阵,可以是实数也可以是复数 ％fs是输入码元的比特率 ％fd是多普勒频移 ％n_delay是多径信道的径数 ％t_delay是多径信道各径的时延时间 ％p_delay是多径信道各径的功率db值 (Of the multipath channel simulation input symbol is a line matrix, can be a real number can also be plural fs is the input symbol of the bit rate fd is the Doppler frequency shift is n_delay multipath channel diameter of a few t_delay is multipath channel time delay of the Path p_delay is multi-path channel the power of the diameter db value)

matlab编写的图像边缘直方图提取程序，最后结果包含了归一化边缘梯度直方图（矩阵第-行），相应量化区间均值（矩阵第二行），相应量化区间均方差（第三行），具体见从程序，有注释(write histogram matlab image edge extraction procedures, the final result contains a normalized edge gradient histogram (Matrix- line), corresponding quantization interval mean (matrix second row), corresponding quantization interval mean square error (third row), see in particular from the program, there is a comment)
