Description: 一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，采用（7，4）循环码对信源做信道编码，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，再对信号进行信道解码，画出采用信道编码技术和不采用信道编码技术的误比特率图。-First, this program uses 16QAM modulation mode, for a string of two binary source is modulated, using (7,4) cyclic code of the source-channel coding to do with a raised cosine roll-off function for base-band modulation, and then transferred to a high frequency channel in the channel by adding Gaussian white noise, the use of matched filter demodulation, demodulation constellation plot, using the minimum Euclidean distance decoding decision, and then right channel signals, decoding, channel coding techniques used to draw and non- channel coding techniques using bit error rate plans.

Description: 本源码是基于MATLAB实现车牌识别并语音播报。
本系统针对家庭小型车蓝底白字车牌进行识别。根据彩色图像的RGB比例定位出近似蓝色的候选区域。但是由于RGB三原色空间中两点间的欧氏距离与颜色距离不成线性比例，在设定蓝色区域的定位范围时不能很好的控制。因此造成的定位出错是最主要的。这样在图片中出现较多的蓝色背景情况下识别率会下降，不能有效提取车牌区域。对此本文提出了自适应调节方案。对分割出来的区域进行识别调整。根据长宽比，蓝白色比对候选区域进行多次定位。最终找到车牌区域。
对字符正确识别之后，用事先对对每一个字符的录音根据对应字符顺序播放。在对车牌区域识别出错、字体分割出错时程序暂停，并有语音提醒。-The source is based on MATLAB license plate recognition and voice broadcast. The system for the small family car blue and white license plate recognition. Approximate positioning of the blue color candidate area based on the ratio of RGB images. However, due to the RGB color space, the Euclidean distance between two points is not a linear scale and color distance, in the blue region of the positioning range setting is not well controlled. Therefore, the positioning error is the main cause. This appears in the picture under a blue background more recognition rate will drop, can not effectively extract the license plate area. This paper presents an adaptive adjustment program. On the segmented regions to identify adjustments. According to the aspect ratio, blue and white area than the candidate repeatedly positioning. Finally found the license plate area. After correctly identify the characters, prior to use for recording each character according to the corresponding sequence of characte Platform: |

Description: In this work, the Mel frequency Cepstrum Coefficient
(MFCC) feature has been used for designing a text
dependent speaker identification system. The extracted
speech features (MFCC’s) of a speaker are quantized to a
number of centroids using vector quantization algorithm.
These centroids constitute the codebook of that speaker.
MFCC’s are calculated in training phase and again in testing
phase. Speakers uttered same words once in a training
session and once in a testing session later. The Euclidean
distance between the MFCC’s of each speaker in training
phase to the centroids of individual speaker in testing phase
is measured and the speaker is identified according to the
minimum Euclidean distance. The code is developed in the
MATLAB environment and performs the identification
satisfactorily. Platform: |

Description: /* A C++ version of Matlab's qamdemod(y, M, varargin)
* Align each symbol to the nearest constellation points by minimum Euclidean distance.
* The function only consider rectanglular constellation diagram and grey code.
* The input is assumed to have been downconverted into baseband.
* I is the I component of phase and Q is the Q component of phase.
* The I and Q should be NxM or 1xM matrix/vector, in which the N indicate the subchannels and M indicates the symbols.
* The function treats each row as a subchannel and normalizes them respectively.
