The invention relates to transmission of data with spectrum-spreading by means of chaotic signals. The invention makes it possible to develop straight chaotic communication systems, in which data is introduced into a chaotic signal which is generated directly within a band for data transmission. The aim of the invention is achieved by formation of a broadband data carrier required for transmission with the aid of a chaotic dynamic system whose structure is presynthesised in accordance with predetermined characteristics of said data carrier in such a way that the chaotic system can form a broadband data carrier in the form of a chaotic data carrier displaying the requisite spectral characteristics. Modulation of the chaotic data carrier occurs by forming a chaotic radio and optical impulses therefrom having a predetermined duration and predetermined time intervals therebetween with respect to a transmitted data signal. Reception and demodulation on the receiving end is carried out with the aid of the dynamic system co-ordinated in relation to the behaviour thereof with the chaotic dynamic system of the transmission end. <IMAGE>
