Discrete chaotic signals with a high information capacity are developed and studied on the basis of nonlinear chaotic dynamic systems. The structural and fractal complexity of pseudorandom integer and binary sequences is analyzed. A model digital spread-spectrum radio channel is used to show experimentally that the chaotic algorithms developed can be applied efficiently in various radio facilities, such as telecommunications, radar, and navigation systems. A technique is developed for forming a reproducible irregular fractal structure involved in frequency-independent fractal antennas with a given fractal dimension. An integer chaotic algorithm with retardation is employed to generate a pseudorandom sequence.
