Research of Synchronization Algorithm in Cooperative Relay Systems
|
Abstract:
The estimation of multiple timing offsets and multiple frequency offsets in cooperative relay system is investigated. A synchronization sequence based on constant amplitude zero auto-correlation sequence is constructed. Furthermore, the corresponding synchronization algorithms are proposed, which only need auto-correlation and cross-correlation operations. Simulation results show that the proposed preamble and synchronization algorithms can achieve satisfactory performance in cooperative relay system.
