文摘

A high-speed preambleless timing synchronization method is proposed with accurate timing offset estimation and smaller standard deviation (SD). The proposed algorithm has lower computational complexity for hardware implementation. Performance is robust to carrier frequency offset (CFO) and irrespective of channel length with realistic SNR assumption for wireless control networks (WCN).
