Abstract

This paper discusses the design of soft handoff algorithms for cellular communication systems based on signal-strength measurements. The handoff process is modeled as a hybrid system and handoff design is cast as an optimization problem based on such a model. Performance is evaluated in terms of call quality, average number of active base stations and average number of active set updates. Preliminary designs based on selective diversity combining are investigated. A suboptimal handoff algorithm, which achieves a tradeoff between these three performance criteria, is obtained using principles of dynamic programming.
