چکیده
In this report, we consider the performance of trellis coded multilevel differential phase-shift-keying (MDPSK) over Rician and Rayleigh fading channels. For operation at L-Band, this signaling technique leads to a more robust system than the coherent system with dual pilot tone calibration previously proposed for UHF. The results are obtained using a Combination of analysis and simulation. The analysis shows that the design criterion for trellis codes to be operated on fading channels with interleaving/ deinterleaving is no longer free Euclidean distance. The correct design criterion for optimizing bit error probability of trellis coded MDPSK over fading channels will be presented along with examples illustrating its application.

A Brief Survey of Channel Models for Land Mobile Satellite Communication
The last review of the modeling of the land mobile satellite channel was done by Karaliopoulos and Pavlidou in 1999. Since then a lot of work has been done to model the land mobile satellite channel. In this paper an up-to-date review of the modeling of the land mobile satellite channel is presented. We look at the various physical characteristics that influence communications in the land mobil...

متن کاملPhysical-statistical model for the land mobile-satellite channel applied to satellite/HAP-MIMO
This paper derives a physicalstatistical land mobile-satellite/HAP propagation channel model that can predict joint statistical time series and power-spatial-delay profile data in a multi-antenna mobile, multi-satellite scenario, and is compared with published measurement data. The model is then used to estimate the required satellite and HAP antenna separation to achieve an uncorrelated Satell...
متن کاملElevation-dependent Channel Model and Satellite Diversity for NGSO S-PCNs - Vehicular Technology Conference, 1996. 'Mobile Technology for the Human Race'., IEEE 46th
In this paper we propose an elevation-dependent Rice Rayleigh/lognormal channel model for communications of personal and mobile users via non-geostationary satellites (NGSO S-PCNs). Based on this channel model, we discuss the performance of satellite diversity for NGSO SPCNs. The parameters of the channel model are derived from channel measurements, which have been carried out for different ele...
