https://doi.org/10.1007/978-3-663-07522-6on signal is not a pure sine wave but a repetitive signal with a known period and waveform. In both cases, the prediction process consists of first performing a Fourier analysis of the source signal, then treating each harmonic (or group of harmonics in a given bandwidth) as a sine wave for calculating radiation.
