Executive Summary

In this paper, the authors evaluate the Cramer-Rao Bounds (CRB) for the estimation of the Carrier Frequency Offset (CFO) for general QAM modulations with no knowledge of the transmitted sequence (blind operation) in Frequency Hopping (FH) based short burst mode mobile radios. They investigate the blind CFO estimation problem in FH based mobile system that uses multiple short narrow-band bursts in different frequency channels for the transmission of one packet. Joint blind channel and CFO estimation over multiple frequency bursts is considered.
