A time-frequency smoothing algorithm for cyclic spectral analysis
Richard S. Roberts · University of North Texas Digital Library (University of North Texas) · 1992
A hybrid smoothing algorithm is described that smooths first in time and then in frequency. The time-frequency smoothing algorithm is designed to compute estimates of the cyclic (cross) spectrum along lines of constant cycle frequency. A variation on the algorithm, one that incorporates the One Bit Spectral Correlation Algorithm (OBSCA), is also described. A simulation study is presented that evaluates the algorithms.
