Abstract

See full text

A method for performing a handoff for a mobile device from a first radio station to a second radio station. The method includes buffering a first media data set that is received through the first radio station. The method also includes cross-correlating a tail portion of the first media data set and a head portion of a second media data set to generate a cross-correlated media data set, if the second media data set is received through the second radio station. The method further includes synthesizing, using a modeled portion of the first media data set, a synthesized media data set, if no media data is received through the second radio station within a threshold. The method further includes extending the first media data set to generate an extended media data set, if no media data is received through the second radio station at the threshold.
