METHODS FOR OVER-THE-AIR BLIND SYNCHRONIZATION OF TWO OFDMA-BASED NETWORKS THAT MINIMIZES INTERFERENCE AND BY USING AN EXTENDED CORRELATION WINDOW LENGTH |
摘要 |
<p>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.</p> |
