In this paper we address the problem of frequency offset estimation from non-periodic training sequences used in packet transmission over frequency-selective channels and additive white Gaussian noise. Based on polynomial approximations of the sin an

In this paper we consider a discretized version of the problem of optimal beam-from design for stationary radar target localization in the presence of white Gaussian noise. We show that the finite-horizon solution to this problem is equivalent to the
