本文提出了一种新的方法来估计移动的站（MS）在一个典型的宏小区的速度。建议的估计器使用的自相关函数的瞬时频率（IF）的接收信号在MS天线。在阴影，加性噪声和非各向同性散射的存在下，所提出的估计的性能进行了研究分析。它被证明，不同于现有的速度估计，基于IF的估计是强大的阴影。
This paper presents a novel method for estimating the velocity of a mobile station (MS) in a typical macro-cell. The proposed estimator uses the auto-correlation function of the instantaneous frequency (IF) of the received signal at the MS antenna. The performance of the proposed estimator in the presence of shadowing, additive noise, and non-isotropic scattering is studied analytically. It is proved that, unlike existing velocity estimators, the IF-based estimator is robust to shadowing.
