本文通过对男性和女性声音的语音特征的研究,发现男女声的基音频率存在较大的差异,并设计了基于基音频率分析的男女声识别系统。男女声识别系统由以下三个模块电路构成:话筒放大器,低通滤波器,半波整流电路,单片机测量控制模块。话筒放大器采用NE5532P音前置芯片,对语音信号进行放大;八阶低通滤波器MAX293完成基音信号的提取;单片机STC12C5410AD实现频率测量和控制输出功能。经仿真与电路实测,男女声的识别效果良好。(In this paper, the voices of male and female voice characteristics of the findings of a study of the fundamental frequency of the sound of men and women there is a big difference, and the design of frequency analysis based on the pitch of the voice recognition system for men and women. Voice Recognition System for men and women from the circuit the following three modules: the microphone amplifier, low-pass filter, half-wave rectifier circuit, single-chip measurement control module. NE5532P sound using the microphone pre-amplifier chip amplification of voice signals eight MAX293-order low-pass filter to complete the extraction of pitch signal STC12C5410AD single-chip realization of the frequency of measurement and control output. By circuit simulation and measurement, the identification of male and female voices well.)

Signal-Processing-for-Mobile-communications
本书不仅回顾了通信信号处理的经典研究领域,如自适应均衡、信道建模和识别、多用户检测和阵列处理,而且分析研究了一些新领域,如自适应编码调制、多输入多输出(MIMO)系统、分集合并和时频分析。此外,本书还探讨了神经网络、蒙特卡洛马尔可夫链和混沌等新兴技术,并对未来移动通信具有发展前途的方法进行了很好的概括性阐述。(The book investigates classical SP areas such as adaptive equalization, channel modeling and identification,
multi-user detection, and array processing. It also investigates newer areas such as adaptive coded
modulation, multiple-input multiple-output (MIMO) systems, diversity combining, and time-frequency
analysis. It explores emerging techniques such as neural networks, Monte Carlo Markov Chain (MCMC)
methods, and Chaos. It offers an excellent tutorial survey of promising approaches for future mobile
communications such as cross-layer design in multi-access networks and adaptive wireless networks.)
