Taha X. Methods of maintenance the quality of communication systems

Object - processes of ultra-wide band (UWB) admission capacity to functioning of radio telecommunication systems. Purpose - quality assurance in radio telecommunication systems of UWB radio admission capacity in the conditions of changing parameters of the signal emission, propagation and reception. Methods - probability theory, optimization theory, theory of estimation and control, space-time signal processing, mathematical modeling. Results - the method for bit error probability in telecommunication systems by harmonizing the UWB radio spectrum signal and amplitude-frequency characteristic of receiver by applying a correction of scaling factors, which influence the form of impulses, depending on the results of measuring radio channel characteristics is improved; further development of a method to increase the UWB communication systems range; further development of the method of increasing further development of the method of increasing bandwidth due to spatial separation of channels. It is introduced - in the research scientific work № DR 0111U002627; used in learning process in the discipline "Broadband telecommunication systems". Sphere of application - telecommunication systems
