Abstract :
A method has been proposed for estimating the frequencies of sinusoids in additive white Gaussian noise. The method is an approximation to Kumaresan\´s "improved Pisarenko" method, which can be thought of as the computation of an FIR notch filter with zeros at the signal frequencies. The new algorithm consists of subtracting a small ε from the
