“…First of all, one should mention various methods using chaotic signal fragments for transmitting digital information by means of position modulation (PM) [ 16 , 17 , 18 , 19 ], frequency modulation of the carrier by a chaotic signal [ 20 ], and the use of discrete systems (maps) with chaos to implement frequency hopping [ 21 ]. Chaotic sequences are used to modulate the position and sign of UWB ultrashort pulses (USP) [ 22 , 23 , 24 , 25 , 26 ] in the framework of position modulation, where symbols are encoded by USP sequences with chaotic intervals between them.…”

A modulation method is proposed for generating identical UWB chaotic radio pulses using an analog generator of chaotic oscillations. The problem is on the edge of two contradicting requirements: (1) theoretical ability to produce a huge number of various-shape signals, because of high sensitivity to the initial conditions of the generator; (2) the necessity to reproduce oscillations of the same shape both in the receiver and in the transmitter for the implementation of coherent methods of signal processing. The considered method allows us to resolve this contradiction. A single-transistor chaotic oscillator with single power supply and frequency range 100 to 500 MHz is proposed. A mathematical model of the generator (a system of ODEs) was derived. A method of generating chaotic radio pulses with a reproducible shape that could be varied in a manner that is controlled and natural for UWB radio by means of changing the supply voltage of the chaotic oscillator is shown. The mathematical model of the generator is simulated numerically and proves the proposed ideas. The shaping and the replicability of UWB pulses was experimentally proven in an analog domain on a testbed with four instances of the chaotic generator.

A method for generating chaotic radio pulses using an analog generator of chaotic oscillations is proposed. The method makes it possible to reproduce the pulse wave-form both by the same generator instance and by different instances of structurally identical generators. The pulse waveforms are controlled by the supply voltage of the generator. To prove the concept an experimental test-bed consisting of four identical generators of 100–500 MHz band has been developed. The proposed method can be applied both for coherent reception of chaotic UWB oscillations in the microwave band and for beamforming.
