On the choice of elementary signals for complex signal radio systems

It widely uses complex signals based on code sequences in digital communication and radar systems. It pays most attention to code sequences analysis, synthesis, and implementation while developing such systems. Significantly less attention is paid to the shape of elementary signals (ES) constituting a complex signal. This work aims at a comparative analysis of the parameters of several known ES in terms of the rate of spectrum decrease and the accuracy of measuring the time position. Recommendations are given for choosing the best ES based on the criterion of unconditional preference. This paper aims in comparative parameter analysing of several known ESs from spectrum decrease rate and time position measurement accuracy points of view. Recommendations are given on choosing the best ES based on the unconditional preference criterion.
