AfJstmct— In this paper, impact of phase noise on CDMAbased satellite communication system is analyzed and simulated. Satellite channel is modeled as combination of Rician fading and shadowed Rayleigh fading channels. The nonlinear Fokker-Planck method is employed to analyze the firstorder PLL (phase locked loop) performance. Phase noise is m,sdeled as Tikbonov distribution. The performance is ...

In the paper various issues in personal satellite communications are addressed. Basic geostationary and non-geostationary satellite constellations are considered. The narrowband and wideband characterization of the mobile satellite channel and related system implications are discussed. Satellite diversity is presented as a measure to overcome signal shadowing. The capacity of TDMA and CDMA mult...
