Simulation of Adjacent Channel Interference in a UHF Satellite System

Abstract

In this thesis, the adjacent channel interference in a ultra high frequency (UHF) satellite channel is evaluated by simulation differential binary phase-shift keying (DBPSK) is compared with continuous phase frequency-shift keying (CPFSK). First, a measure the interfering power is obtained and a method to compute carrier-to-interference ratios in a non-linear channel is developed. Next a DBPSK receiver is simulated when two interfering channels separated in frequency are present, and bit errors are detected and counted Then, coherent reception of minimum-shift keying (MSK) and CPFSK with modulation index h=0.4 are simulated in the same conditions as DBPSK, Finally, noncoherent MSK is analyzed in the same way and a comparative behavior it obtained. It is found that the best performance in the presence of adjacent channel interference is given by coherent reception of MSK. DBPSK, CPFSK, MSK.
