Digitální modulace radiokomunikačních systémů

Abstract

The main task of this bachelor thesis is to point out the importance of digital modulation in radio communications. This report of thesis also includes following aspects such as overall description of modulation formats, the transparent samples to every mentioned modulation created in specific program ,,Matlab Simulink,, as well as it provides a mutual compararison of modulations as result of failing rate of SNR, what is level of signal and level of noise evaluated in specific measurement - decibel. The main aim of theoretical part is to describe the use of digital modulation as it has become commonly used in wireless communication. Theoractical part describes the samples of each modulation, created in Matlab Simulink, where there is every modulation described. In final, there is comparision of all modulations as there are estimated some failures in rate of SNR.
