In this letter we present new and simple closed form expressions for the true Cramér-Rao lower bound (CRB) for data-aided (DA) joint and individual carrier frequency offset and symbol timing estimation from a linearly modulated waveform transmitted over an AWGN channel. The bounds are derived under a carrier-phase-independent (CPI) estimation strategy(More)
In this correspondence, we propose a new feedforward frequency offset or single frequency estimator which is based on a single weighted sample correlation with lag k, computed from N noisy observations. The new estimator is a simple generalization of the unweighted Lank-Reed-Pollon (LRP) estimator introduced in [G. W. Lank, I. S. Reed, and G. E. Pollon, ";A(More)
This work studies the impact of a specific channel time correlation model on the link-level performance of a coded OFDM system that uses iterative channel estimation. When the main focus of extensive simulation campaigns is to measure the overall system performance, it would be desirable to implement low-complexity algorithms that replace the(More)
We present the NEFOCAST project (named by the contraction of "Nefele", which is the Italian spelling for the mythological cloud nymph Nephele, and "forecast"), funded by the Tuscany Region, about the feasibility of a system for the detection and monitoring of precipitation fields over the regional territory based on the use of a widespread network of(More)
