Abstract :
Results of analysis and computer simulations are used to compare two methods of estimating the cyclic polyspectrum. The computational requirements of the two methods are determined and compared. A cycle leakage phenomenon is explained and it is shown that, for a given amount of data, only one of the two methods can be modified to reduce this leakage, but at the cost of increased computations. Numerical examples of measurements of fourth-order cyclic polyspectra are provided to illustrate the leakage problem
