Abstract
A system for the identification of sinusoidal interference signals from a noise signal is provided. The system includes a unit for the estimation () of an autocorrelation matrix ({circumflex over (R)}) of a measured signal (x(t), x(μ·Δt)), composed from the sinusoidal interference signals (A·e, A·e) and the noise signal (w(t), w(μ·Δt)), a unit () for frequency estimation, and a unit () for power-level determination of the spectral lines associated with the sinusoidal interference signals (A·e, A·e) A Fast Fourier Transform filter bank () is additionally provided for the generation of several frequency bands (v) for the measured signal (x(t), x(μ·Δt)), composed of the sinusoidal interference signals (A·e, A·e) and the noise signal (w(t), w(μ·Δt)).
