Prediction of Received Signal Power for Mobile Cellular Systems
Jarno M. A. Tanskanen · 1995
In this subproject, prediction of signal power received from a mobile station by a base station is investigated. The motivation for this work arises from the power control requirements essential to Direct Sequence Code Division Multiple Access (DS-CDMA) systems. The results are also applicable to other non-frequency-hopping systems as well. This paper gives a short overview to some main aspects and results of the work. A class of finite-impulse-response (FIR) type polynomial predictors is investigated with simulations employing two urban mobile radio channel models. The simulations show that FIR polynomial predictors can provide the controller smoothed signal power samples with the signal-tonoise ratio (SNR) improved by ca. 5 dB, without any delaying of the signal.
