Abstract

Fast handoff algorithms for urban microcells using velocity adaptation and corner detection are presented. Three velocity estimators are compared with respect to their accuracy, sensitivity to non-isotropic scattering, capability of detecting when a mobile turns a corner, and response time in typical microcell environments. Simulation results show that velocity adaptive corner detecting handoff algorithms yield faster and more consistent handoff performance than traditional methods
