Cramer-Rao Bound for Joint Carrier Frequency Offset, Symbol Timing Offset and Channel Taps in MC-CDMA Systems

摘要

In this paper, Cramer-Rao bound (CRB) for joint carrier frequency and symbol timing offsets and channel taps is proposed for multi carrier code division multiple access (MC-^sCDMA) systems. CRB provides a benchmark by which, the performance of any unbiased
