turbo码的编码与译码，交织器 coding and decoding of turbo, interleaver(coding and decoding of turbo, interleaver, almost regular permutation)

1、对给出的数字0、1序列进行BPSK调制,调制成正负极性，并进行傅里叶变换. 2、滚将升余弦窗设计(1、making BPSK modulation for given 0、1 data serial.And make FFT change. 2、Raised-cosine window)

实验要求：在一张图上绘制三种二进制信号（即反极性信号、开关信号和正交信号）的误码率。这三种信号可以在几何上用“信号空间”中的点来表示。在反极性信号情况下，信号是±s(t)，每个都有能量E。开关信号也是一维信号，所以两个信号为0和s(t)，正交信号我们上课已讲过。要求信噪比为0：12dB。(Experimental requirements: to draw a diagram of three binary signals (i.e., reverse polarity signal, the switching signal and quadrature signal) BER. These three signals can be in the geometric point in the signal space. In the reverse polarity signal case, the signal is s (t), each have energy E. The switching signal is also a one-dimensional signal, so the two signals is 0 and s (t), the quadrature signals teach us have talked. Signal-to-noise ratio to 0:12 dB.)

Accepts two bounding vectors and produces an equally spaced matrix with unique fixed step row-wise

在复杂的电子系统中，影响信号接收的很多噪声为非高斯噪声，这些噪声是没有预料到的，以致破坏了接收机的功能，研究表明：这些噪声可以看成双模噪声，双模噪声从整体上讲属于非高斯噪声。(In complex electronic systems, many of the signal received by a non-Gaussian noise, the noise is not anticipated, resulting in damage to the receiver function, research shows that: the noise can be regarded as dual-mode noise, dual-mode noise As a whole is non-Gaussian noise.)

用matlab读取PGM格式图片，简单易懂，参考性强(Matlab read the PGM format picture, straightforward reference)

语音信号处理的一些常用工具及算法，希望对大家有用(Speech signal processing algorithms commonly used tools and, in the hope it would be useful)

This function produces an image of a 3D object defined by matrix a(l,m,n) in terms of voxels the image is a view after rotating the object by angles alfa and beta (in degree) b is the image and d is its ditance to the viewer matrix The first figure depicts the object using only its gray level values The second image depicts the object using some lighting effect rotate3d may be used for reorientation but the obtained image is planner
