Iterative Spectrum Analysis of Nonuniformly Undersampled Wideband Signals
The problem of how to use already existing fast algorithms, first of all FFT, for alias-free estimation of nonuniformly sampled wideband signal parameters in the frequency domain is considered and an iterative approach to its solution is suggested. It is applicable for signal analysis in a wide frequency range with the highest frequency considerably exceeding the mean sampling rate. The essentials of signal processing according to the developed method are discussed. The results achievable in the suggested way are illustrated by an example.
