Efficient ML Direction of Arrival Estimation assuming Unknown Sensor Noise Powers
J. Selva
This paper presents an efficient method for computing maximum likelihood (ML) direction of arrival (DOA) estimates assuming unknown sensor noise powers. The method combines efficie…
Wideband Subspace Estimation Through Projection Matrix Approximation
J. Selva
In this paper, we present a wideband subspace estimation method that characterizes the signal subspace through its orthogonal projection matrix at each frequency. Fundamentally, th…
Non-iterative Type 4 and 5 Nonuniform FFT Methods in the One-Dimensional Case
J. Selva
The so-called non-uniform FFT (NFFT) is a family of algorithms for efficiently computing the Fourier transform of finite-length signals, whenever the time or frequency grid is nonu…
FFT Interpolation from Nonuniform Samples Lying in a Regular Grid
J. Selva
This paper presents a method to interpolate a periodic band-limited signal from its samples lying at nonuniform positions in a regular grid, which is based on the FFT and has the s…
Signal Estimation from Nonuniform Samples with RMS Error Bound -- Application to OFDM Channel Estimation
J. Selva
We present a channel spectral estimator for OFDM signals containing pilot carriers, assuming a known delay spread or a bound on this parameter. The estimator is based on modeling t…
Efficient Maximum Likelihood Estimation of a 2-D Complex Sinusoidal Based on Barycentric Interpolation
J. Selva
This paper presents an efficient method to compute the maximum likelihood (ML) estimation of the parameters of a complex 2-D sinusoidal, with the complexity order of the FFT. The m…
