Mobile unit velocity estimation in microcellular systems using the ZCR of the instantaneous frequency of the received signal
نویسندگان
چکیده
This paper presents a new estimator for the velocity of a mobile station in micro-cellular systems. The proposed estimator is based on the zero-crossing rate of the instantaneous frequency of the received signal. The effects of additive noise, scattering distribution, and shadowing on the proposed velocity estimator are analyzed. The IF-based velocity estimator outperforms the conventional estimators in the presence of shadowing.

Estimation of the velocity of mobile units in microcellular systems using the instantaneous frequency of the received signals
Handover processes in micro-cellular systems are more involved than in cellular systems. In particular, micro-cellular systems suffer from the so-called corner effect where lineof-sight between the mobile station and the base station is suddenly lost when the mobile rounds a corner. As a result, the received signal drops rapidly below threshold level and the call can be lost. It has been shown ...
متن کاملEstimation of the mobile station velocity in micro- cellular systems with non-isotropic scattering
This paper presents a new method for estimating the velocity of a mobile station (MS) in a typical micro-cellular system with non-isotropic scattering. The proposed estimator uses the zero-crossing rates of the in-phase component, and the means of the instantaneous frequency (IF) and the absolute IF of the received signal at the MS antenna. It is also shown that using the above mentioned statis...

One of the important issues in many of array systems such as Radar, Sonar, Mobile, and satellite telecommunications is the estimation of DOA of narrowband received signal. CRB is very important in evaluation of parameter estimation. CRB is the lower bound estimation error variance for any unbiased estimation. In this paper, the array antenna with equal distance arrays is extended in two separat...
