ANALYSIS OF THE PROPERTIES OF ULTRA-WIDEBAND SIGNALS AFFECTING THE SECRECY AND RELIABILITY OF DATA TRANSMISSION IN RADIO COMMUNICATION SYSTEMS

The analysis of the use of sequences of ultra-wideband (UWB) signals formed on the basis of BPSK modulation to ensure the secrecy and reliability of data transmission in radio communication systems is carried out. Their properties were evaluated using BDS-statistics and peak factor indicators. As a result of the conducted research, it was found that for the selected research conditions, the UWB sequences based on the solution of the Euler – Lagrange equation, characterized by greater secrecy from an outside observer than other studied UWB sequences, are generally suitable. It is also shown that all the studied UWB sequences have an acceptable peak factor value. It is noted that UWB sequences based on widely used pulses, for example, Gauss monocycles, as well as standardized radio communication systems, do not fully ensure the secrecy of data transmission in radio communication systems, therefore, it is impractical to use them in UWB radio communication systems with high requirements for ensuring the secrecy of data transmission. The conducted research has made it possible to supplement knowledge about UWB sequences to ensure covert and reliable data transmission in radio communication systems.
