On the Correlation Matrices of Trigonometric Product Functions

Sets of waveforms called TPF's, which are products of trigonometric functions, may have application in communications technology, network analysis and signal processing. This communication briefly reviews the characteristics of TPF's and presents methods for calculating their cross-correlation coefficients when 1) all TPF's in a set have harmonic factors with the same set of values, and 2) the harmonic factors have different values.
