Title: A handover decision procedure based on the minimization of Bayes criterion
Author: Senadji, B; Tabbane, S; Boashash, B
Abstract: In mobile radio communications, inter-cell handover algorithms represent a critical issue for future pico and micro cellular systems. Two conflicting criteria must be optimized: the number of unnecessary handovers between two adjacent base-stations and the number of lost calls. A handover algorithm is proposed which utilizes a decision criterion such as signal strength. It allows for optimal trade-off between the number of unnecessary handovers and the number of lost calls. It is based on Bayes criterion which is commonly used in detection and estimation techniques. An optimal threshold q is derived using this criterion, which depends on the decision criterion and is dynamically adjusted by taking into account the observations. The decision of handover is made by comparing the distance d between the mobile station and the current base-station to this threshold q.
Description: This is a DSP application to hand-over procedures in mobile communications. (The most recent upgrade of the original software package that calculates Time-Frequency Distributions and Instantaneous Frequency estimators can be downloaded from the web site: www.time-frequency.net. This was the first software developed in the field, and it was first released publicly in 1987 at the 1st ISSPA conference held in Brisbane, Australia., and then continuously updated). A companion is the comprehensive book on Time-Frequency Signal Analysis and Processing available at: http://www.elsevier.com/locate/isbn/0080443354
