Abstract
A method for radiosynchronization of base stations in a simulcasting network which includes a plurality of base stations to be synchronized, comprising the following steps: a.) a first set of base stations transmitting respective synchronization signals; b.) a second set of base stations receiving at least one of the respective synchronization signals for the purpose of determining several estimates of synchronization error, where each of the several estimates is an estimate of synchronization error between one of the first set of transmitting base stations and one of the second set of receiving base stations; and, c.) adjusting subsequent transmissions of particular base stations to minimize synchronization errors between base stations within the first or second set to achieve simulcast transmission of all base stations in the network, wherein the adjustment is made based upon the several estimates, and wherein each of the several estimates was obtained based upon a synchronization signal which was either received or transmitted by the particular base station being adjusted.
