Development of communications systems reliably operating in an unfavorable electromagnetic environment is today a challenging problem because of a high density of interfering signals generated by numerous radioelectronic systems (especially in cities) and a large amount of electromagnetic noise of different natures. The search for new types of noise-immune signals is a key direction in designing communications system reliably operating in a noisy environment. Using a fractal wavelet signal as an example, we consider the theoretical and experimental data on synthesizing wide-band fractal signals on a 2-GHz sinusoidal carrier and discuss their basic properties. It is shown that such signals have self-similar fractal spectra and a high noise immunity and, therefore, can be applied in noise-immune communications.
