A radio synchronization technique that dispenses with GPS (Global Positioning System) for OFDM (Orthogonal Frequency Division Multiplexing)-based broadband networks is described. UMTS (Universal Mobile Telecommunications System) employs three main mechanisms, a node, transport channel and radio interface synchronization. The RNC (Radio Network Controller) is used as a key network component for the centralized synchronization mechanism. Here, we explore a more accurate and simpler asynchronous technique for broadband networks from the perspective of a distributed manner, where MSs (Mobile Stations) play an important role in timing adjustment. Propagation delay and the hierarchical synchronization mechanism are taken into account in the mathematical analysis.
