多输入多输出（MIMO）系统是在无线通信智能天线技术的基础上发展起来的，其主要特点就是在通信系统的收发两端采用多天线配置，以解决未来移动通信系统大容量、高速率传输和日益紧张的频谱资源间的矛盾。(Multiple-input-multiple-output (MIMO) is a communication technology that multiple antennas are set at transmitters and/or receivers. The system capacity and frequency spectrum efficiency of communication systems can be improved by this technology without extra frequency bandwidth and with no additional power expenditure . )

对利用录音设备对手机、电话等按键式密码输入终端进录音盗取银行卡密码的不法行为进行技术分析，利用MATLAB软件编程对按键式密码输入终端的按键音进行音频分析，基于短时能量和过零率对所采集的音频文件进行端点检测，提取出单个拨号音，然后对处理后的音频进行频谱分析、对比，从而识别按键式密码输入终端的按键音。(On the use of recording equipment on the phone, telephone touchtone input terminal password into the recording steal bank card passwords wrongful conduct technical analysis using MATLAB software programming for touch-tone touchtone password input terminal for audio analysis, based on short-term energy and zero-crossing rate of the acquired endpoint detection audio files, extract single dial tone, and then processed audio spectrum analysis, comparison, to identify key tone touchtone password input terminal.)
