Abstract :
A complex form of a fast frequency estimation technique based on the quotient-difference (QD) algorithm is presented. The complex stochastic process is modeled as a sum of nonharmonically related damped exponentials. This algorithm computes the zeros of the predictor polynomial in a single step, directly from the data and has computational complexity on the order of Np
