Low‐complexity frame synchronisation method for IEEE 802.15.4 systems

A low‐complexity frame synchronisation method for IEEE 802.15.4 systems is proposed. An autocorrelation function is utilised for reducing computational complexity for fine timing estimation instead of a cross‐correlation function. To provide accurate estimation results, residual errors are compensat...

Zusammenfassung:	A low‐complexity frame synchronisation method for IEEE 802.15.4 systems is proposed. An autocorrelation function is utilised for reducing computational complexity for fine timing estimation instead of a cross‐correlation function. To provide accurate estimation results, residual errors are compensated in the step of detecting start‐of‐frame delimiter symbols. The complexity of the proposed method for fine timing estimation is
