代码说明:

  时频分布已被用来提供高分辨率表示大量的信号处理应用程序。然而,高分辨率和准确瞬时频率(如果)估计通常依赖于分布和使用信号相位函数的复杂性。(The time-frequency distribution has already been used to provide high resolution said a lot of signal processing applications. However, high resolution and accurate instantaneous frequency (if) estimates usually depends on the distribution and use of the complexity of the signal phase function.)

  • identify
    说明:  通信信号的调制信息包含在信号的瞬时幅度、相位、频率的变化之中,不同的信号其频谱也呈现不同的特征,通过提取瞬时幅度、相位、频率以及频谱的参数统计特征,可以识别不同的通信信号。通常是利用对瞬时幅度、瞬时相位,瞬时频率和信号功率谱进行某种变换而得到可以明显区分各种信号的特征参数。(Communication signal modulation information is contained in the signal instantaneous amplitude, phase, frequency changes, the spectrum of different signals also show different characteristics, by extracting the instantaneous amplitude, phase, frequency and statistical characteristics of the parameters of the spectrum, you can identify different communication signals. Usually by the use of instantaneous amplitude, instantaneous phase, instantaneous frequency and signal power spectrum a transformation which can be clearly distinguished by the characteristic parameters of various signals.)
