In this paper the influence of a stationary white noise on the estimation of a sine-wave amplitude by means of the three-point Interpolated Discrete Fourier Transform (IpDFT) method is investigated. The expression of the amplitude estimator variance is derived when the H-term maximum sidelobe decay window (H ?? 2) is employed. Based on the derived expression the statistical efficiency of the three-point...
This paper proposes a computationaly-efficient procedure dedicated to time-domain phase noise (PN) modeling of a phase-locked loop (PLL)-based frequency synthesizer in a radio-frequency (RF) context. The structure proposed is able to describe any kind of PN including thermal and flicker noise regions using time-domain equations. The design process of the phase noise modeling process is detailed. An...
This paper proposes an efficient implementation of the blind Self-Adaptive Decision Feedback Equalizer (SA-DFE) presented in [1]. This innovative low-complexity equalizer has the particularity of adjusting its structure with the difficulty of the channel. The equalizer switches to a linear recursive equalizer when the channel is very dispersive and to a decision-directed DFE when the output of the...
