数字频率调制又称频移键控（FSK），二进制频移键控记作2FSK。数字频移键控是用载波的频率来传送数字消息，即用所传送的数字消息控制载波的频率。2FSK信号便是符号“1”对应于载频，而符号“0”对应于载频（与不同的另一载频）的已调波形，而且与之间的改变是瞬间完成的。 (Digital frequency modulation called frequency shift keying (FSK), binary frequency shift keying recorded as 2FSK. Digital frequency-shift keying is the carrier frequency to transmit digital information, that is, the number of messages transmitted with the control of the carrier frequency. 2FSK signal is the symbol of "1" corresponds to the carrier frequency, while the symbol "0" corresponds to the carrier frequency (with a different carrier frequency to another) and modulated waveform, but also between the change was instantaneous.)

公交调度需要考虑公司和乘客的多方利益，因此要根据实际情况做出灵活有效的调度方案。(Bus Dispatch to consider a multi-stakeholder companies and passengers, so to make a flexible and effective scheduling scheme according to the actual situation.)

巴特沃斯滤波器，主要实现的是低通信号，此功能模块的低通曲线很符合理想的幅频特性。(Butterworth filter, the main achievement is low traffic numbers, the low-pass curve is consistent with this function module ideal frequency characteristics.)

验模态分解（Empirical Mode Decomposition,简称EMD）是一种自适应信号分解方法,主要应用于非线性非平稳的信号。整体平均经验模态分解（Ensemble Empirical Mode Decomposition,简称EEMD）解决了EMD中出现的模态混合问题。(Ensemble Empirical Mode Decomposition)

微多普勒效应在雷达成像中的应用，并且将微多普勒的优点发挥到极致。同时在其中有很多的例子可以供学习。(Micro-Doppler effect in radar imaging applications, and advantages of the micro-Doppler to maximize. While there are a lot of examples for learning.)

EM算法，在统计计算中，最大期望（EM）算法是在概率（probabilistic）模型中寻找参数最大似然估计或者最大后验估计的算法，其中概率模型依赖于无法观测的隐藏变量（Latent Variable）。(EM algorithm)
