Phase-optimised linearly-constrained minimum-variance beamformers
Hugh L Kennedy
A procedure for the determination of the optimal group-delay of a Linearly-Constrained Minimum-Variance (LCMV) beamformer is proposed. Two ways of selecting the optimal delay are r…
Recursive and non-recursive filters for sequential smoothing and prediction with instantaneous phase and frequency estimation applications (extended version)
Hugh Lachlan Kennedy
A simple procedure for the design of recursive digital filters with an infinite impulse response (IIR) and non-recursive digital filters with a finite impulse response (FIR) is des…
Digital Filters for Instantaneous Frequency Estimation
Hugh Lachlan Kennedy
This technical note is on digital filters for the high-fidelity estimation of a sinusoidal signal's frequency in the presence of additive noise. The complex noise is assumed to be…
Lecture notes on the design of low-pass digital filters with wireless-communication applications
Hugh L. Kennedy
The low-pass filter is a fundamental building block from which digital signal-processing systems (e.g. radio and radar) are built. Signals in the electromagnetic spectrum extend ov…
The leaky integrator that could: Or recursive polynomial regression for online signal analysis
Hugh L Kennedy
Fitting a local polynomial model to a noisy sequence of uniformly sampled observations or measurements (i.e. regressing) by minimizing the sum of weighted squared errors (i.e. resi…
Digital filters with vanishing moments for shape analysis
Hugh L. Kennedy
Shape- and scale-selective digital-filters, with steerable finite/infinite impulse responses (FIR/IIRs) and non-recursive/recursive realizations, that are separable in both spatial…
