FIG. 18B is waveform diagrams illustrating example broadband carrier signals 1828, in accordance with an embodiment. The waveforms shown in FIG. 18B include the broadband carrier signals 1828 and a power spectrum 1862 of the broadband carrier signals 1828.
As shown in FIG. 18B, the broadband carrier signals 1828 contain many frequency components including a wide range of frequencies that can be transmitted, recorded, and manipulated. In one embodiment, the broadband carrier signals 1828 may include a number of frequency components having nearly equal power or amplitude at different frequencies, thus giving the broadband carrier signals 1828 a uniform power spectrum 1862. In one embodiment, the broadband carrier signals 1828 may be constructed from a number of discrete samples that are a sequence of serially uncorrelated random variables with zero mean and finite variance. The samples may also be independent and have identical probability distributions. In one embodiment, the broadband carrier signals 1828 may contain many frequency components having a power spectrum 1862 such that the power spectral density (energy or power per frequency interval) is inversely proportional to frequency of the frequency component.
