Opis (srp)

Fundamental problems in wireless mobile telecommunication systems in urban environments are fast and slow fading, and interchannel interference. These problems significantly limit channel capacity and spectral efficiency of transmission. In this dissertation, macrodiversity reception of signals will be considered, aimed at reducing the negative influence of fast and slow fading. Performance of macrodiversity system will be considered when KG fading is present at the inputs of two-branch receiver, i.e. when the receiver is subjected to simultaneous influence of fast and slow fading effects, and interchannel interference. Interference envelope is also considered to be KG distributed, as expected for the considered urban environments. The dissertation will first determine probability density function of the ratio of two KG random variables, and then also the probability density functionof the ratio of signal and interference at the output of SC receiver. Also, cumulative probability, characteristic function and outage probability for the receiver with SC diversity technique in the presence of Nakagami-m and slow Gamma fading and interchannel interference will be determined.
