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.)

详细介绍了802.16的协议，这部分是MAC层，其余正在下载中(details of the 802.16 of the Agreement, which is part of the MAC layer, and the rest were Download)

子类方法不可比父类方法抛出更多的例外。子类抛出的例外或者与父类抛出的例外一致，或者是父类抛出例外的子类型。或者子类型不抛出例外。(Class methods are not comparable to the parent class method throws more exceptions. The subclass thrown exception or thrown with the parent class exceptions, or the parent class throw exception sub type. Do not throw exceptions or sub type. )
