Description: 语音检测的目的是在一串连续的记录信号中将重要的信息分离出来。在电信应用领域，语音检测是必需的。对于自动语音识别，端点检测在分离重要语音信息时是必需的，这样可以产生语音模式或语音模板。-Voice detection is aimed at a string of consecutive records of information important signal will be separated. At the field of telecommunications applications, voice detection is essential. For automatic speech recognition, endpoint detection important voice in the separation when the information is necessary, so that could have a voice pattern or voice template. Platform: |

Description:
The zip file contains several matlab files. These files implement the optimal vlassifier (optimal_classifier.m), a sub-optimal classifier (SOS_STBC_Classifier.m) which is based on Second Order Statistic and a low-complexity sub optimal code-parameter classifier (CP_Classifier.m). See reference [1] for the theoretical background.
Example: To create the fig 3,4 and 5 of the paper, call the routine:
Blind_recognition_STBC2_simulation_results(512,4, PSK ,4)

Description: 语音特征信号识别是语音识别研究领域中的一个重要方面,一般采用模式匹配的原理解
决。语音识别的运算过程为:首先,待识别语音转化为电信号后输入识别系统,经过预处理后用数学方法提取语音特征信号,提取出的语音特征信号可以看成该段语音的模式。然后将该段语音模型同已知参考模式相比较,获得最佳匹配的参考模式为该段语音的识别结果.-Speech characteristic signal recognition is an important aspect in the field of speech recognition research, generally USES pattern matching the original understanding
Definitely. Operation process of speech recognition are as follows: first, after waiting for voice recognition into electrical signal input and recognition system, after pretreatment
Mathematical method was used to extract speech signal, and extracts the phonetic characteristics of signals can be as the segment of speech patterns. And then the
Audio model compared to a known reference model, get the best match the reference pattern for this speech recognition results. Platform: |

Description: 心律失常是一种常见的内科疾病，会对患者的生活及健康造成严重影响。当心律失常发生时，心房和心室收缩程序改变，能使心排血量下降30 左右，从而使血液循环失常。因此，对心律失常进行早期诊断具有重要的临床意义,而利用心音信号识别算法可以快速识别心律失常的病例,有助于提高诊断速度。
-Arrhythmia is a common medical diseases, can cause serious influence to the patient s life and health. When cardiac arrhythmias occur, atrial and ventricular systolic program change, can make the cardiac output fell by around 30 , which makes the circulation of the blood disorder. Early diagnosis of arrhythmia, therefore, has important clinical significance, and the use of heart sounds signal recognition algorithm can quickly identify arrhythmia cases, helps to improve the diagnosis speed.
