| 摘 要： | 本文首先提出了在插入无调制片的匹配滤波接收机条件下，频率衰落信道的瑞利乘性畸变的简单基带离散模型，建立了一个适应多普勒扩展Ｋａｌｍａｎ滤波器，最后作为一个例子估计了序列多普勒扩谱的归一体截止频率，另外文中给出了一个估计归一化截止频率的数字低通滤波器模型。

| Abstract: | This paper presents a baseband discrete-time state-space model for generation of Rayleigh MD(multiplicative distortion) in a frequency flat fading channel.An extended Kalman filter with Doppler spread adaptations is constructed, and with computer simulation analysis, the normalized cutoff frequency sequence is estimated as an example. The new idea to choose the digital lowpass filter model which would generate the normalized cutoff frequency sequence is also proposed. |
