Abstract
A system and method for performing initial synchronization during wireless sector searches. The system includes a first subsystem for coarse timing alignment including a decimator to reduce computational complexity and a long-lag differential correlator, a second subsystem for jointly estimating RTE and FFO utilizing a short-lag differential correlator, and a third subsystem for jointly detecting IFO and SID utilizing segmental FD MFs. The system and method of the present disclosure accounts for intercell interference, ICI, and multipath fading with assistance from inherent diversity.
