“…The comparator at the output of the digital Fourier processor (Fig. 2) compares the information correlation peaks with a shift of T 1 or T 0 for module (10) and determines from them the largest correlation peaks that correspond to the transmitted bit «1» or «0». Thus, the receiver performs unambiguous restoration of the transmitted binary information.…”

Ab s t r a c t. The subject of the study are the organization of wireless transmission of digital information based on ultrawideband signals. The goal is the development of models and methods for organizing broadband wireless communications operating in difficult interference environments. The task is to ensure the stable and safe operation of communication systems. The methodology is based on the method of generating ultra-wideband digital signals and the method of extracting ultra-wideband information signals in the communication channel with interference. The methods used: methods of analytical, simulation and inverse Fourier transform. The following results are obtained. A technique has been developed for wireless transmission of digital information based on ultra-wideband signals, which includes a method for generating ultra-wideband information signals with code spectral modulation and a method for extracting information signals in a communication channel with interference. An assessment of the effect of interference on the quality of the information being restored is performed. A special class of intra-system interference has been identified, which appears due to the multiplicity of delays in the information bit stream T 0 or T 1 . It is shown that their appearance leads to an increase in the bit error when extracting information signals in the communication channel. A mechanism is proposed for eliminating these errors by setting the multiple delays T 0 and T 1 when generating ultra-wideband information signals. Conclusions. The use of communication channels with an ultra-wide frequency band makes it possible to simultaneously implement a set of requirements for the electromagnetic compatibility of telecommunication systems, high-speed transmission of information with high noise immunity with respect to external interference.

Mathematical models of the signals peculiar to communications using the autocorrelation reception of the shift-keyed noise signals are suggested in the present paper. System performance is investigated and the particularities of the bit error probability dependence upon the normalized signal-to-noise ratio and the bandwidth-delay product are revealed. The definition of the optimal value of the signal-to-noise ratio upon power is substantiated and the relevant values are calculated. The performed comparative analysis proved that the communication using the differential noise shift-keying, within which total time delay diversity is applied between the reference and the data signals, possesses the best system performance among the communications considered in this paper.

“…A broadband channel for digital information transmission based on spectral code modulation, first proposed in [27], is considered in [28], at which the transmitter adds the reference broadband noise signal with its copy delayed for the different time intervals, duration of which depends on incoming information binary symbol. In the receiver, an unambiguous reconstruction of the binary symbol stream occurs when performing double spectral processing of the received signal when estimating the position of the information peak of its autocorrelation function takes place.…”

Application of chaotic signals in modern telecommunication facilities and radars is an actual task that can significantly extend functionality of these systems and improve their performance. In this chapter, we propose a concept of chaos-based technique for secure communication and hidden data transmission over an open network channel which is based on a novel method for spectral keying of chaotic signal generated by nonlinear dynamical system with delayed feedback. In the technique developed, the modulating information sequence controls the parameter of nonlinear element, so that it switches the chaotic modes and changes the spectral structure of the signal, transmitted to the communication channel. A noncoherent reception is used for demodulation the information message from received waveform. We start from theoretical justification of the proposed scheme, and show then the numerical simulations and imitation modeling results, as well as demonstrate experimental validation of suggested technique. Also, the communication system reliability and its covert operation efficiency under impact of AWGN in the environment with high-level interferences have been shown by means of evaluation the system anti-jamming capabilities and unauthorized access immunity.
