Attention will be paid to technical methods. Using of a pseudorandom adjustment of the operating frequency, is a frequent change in frequency that occurs under a pseudorandom law, known by a transmitter and receiver. Another way is to dynamically expanding the spectrum of the transmitted signal. Each transmitted bit of information is represented as a sequence of a certain number of code symbols. Significant distribution has gained a way to increase noise immunity based on the use of directed antennas. The last described method will be the "power" method.ukConference proceedings
