Methods for over-the-air blind synchronization of two OFDMA-based networks that minimizes interference and by using an extended correlation window length

Synchronization of a macrocell network with one of its sub networks (e.g., a femtocell network, a microcell network) is important for reducing the level of inter-carrier interference (ICI) that exists between the uplink users of a macrocell network and the sub-network. Even though blind synchronizat...

description Synchronization of a macrocell network with one of its sub networks (e.g., a femtocell network, a microcell network) is important for reducing the level of inter-carrier interference (ICI) that exists between the uplink users of a macrocell network and the sub-network. Even though blind synchronization techniques based on single-user signal conditions are known, the signal models are ineffective in multiuser scenarios and do not provide for reducing ICI effects. A blind synchronization method is disclosed which reduces ICI for sub network communications. Additionally, a method is disclosed which accurately and blindly synchronizes to the first user using an extended correlation window.
