Channel estimation and time synchronization system for HiperLan2 combines functions

摘要

A channel estimation and time synchronization system samples (600) and correlates an OFDM (Orthogonal Frequency Division Multiplexing) Hiperlan frame to get fine and coarse time references (601) with preamble frequency transformation (603) in an offset (602) window to give samples for channel estimation (604) followed by data transform correction (605) and channel equalization (606).
