THEORETICAL-ANALYSIS OF INTERBASE-STATION SYNCHRONIZATION SYSTEMS

This work is targeted toward understanding the performance in terms of residual timing error of the over-the-air autonomous decentralized in terbase-station synchronization system. An exact solution for the unif orm weights case and an approximate solution for the power weights eas e are obtained in closed form. The residual timing error, system stabi lity, and system convergence performance are studied based on the clos ed-form solutions. It is shown that timing can converge very fast for the uniform weights case; the power weights case has loser residual ti ming error measured in terms of standard deviation than that of the un iform weights case when all transmitted power levels are the same.
