Kavasmi A. Enhancing the effectiveness of mobile telecommunication systems in civil aviation on the base increasing sort of the demodulators wideband signals.

Dissertation is devoted to increasing sort of the demodulators wideband signals (WBS) and enhancing the effectiveness of mobile telecommunication systems in civil aviation. An analysis of noise tast is conducted for: noncoherent demodulator of signals with many position frequency modulation (MFM), when ortogonalization is breaked; sincronization canal acystoelectronic furies-processor; demodulator of signals with PCM-MFM. Methods have been developed and optimization problems have been solved for: structures of system WBS, demodulator of WBS with IPM-MFM, wideband systems of aviation radio link. The packet of programs for initiation modeling noncoherent demodulator of WBS have been developed. The research work results have been introduced into the study process and application was found in organization of air traffic control.
