“…This bi-modality is inherent in the models of References [2,3], and has been observed in many other studies, e.g. in Reference [17], which described data at a different frequency band (Ka-band), but still in an urban environment. This bi-modality arises naturally due to our division of the data into two distinct regimes and is in correspondence with models in References [2,3].…”

SUMMARYUsing measured data on average fade duration (AFD) and level crossing rate (LCR), we obtain new analytical expressions for the probability density function (pdf) of received signal envelope in a mobile satellite channel, via a new method. The measured data for an urban environment comes from Kanatas et al. Proceedings of the 1997 International Mobile Satellite Conference, Pasadena, CA, 16-18 June, 1997; 169-175, but the new method is general in nature and can be applied to other environments. The method is less direct than curve-fitting to a histogram of the 'raw' measured fading amplitude data, but is comparable in complexity and yields good results. Our new model is a composite one, similar to other composite models given in the literature, e.g. the Loo and Lutz models, but in contrast to these, the new model affords a completely closed-form expression for the pdf. As with these other composite models, the new model is amenable to the development of computer simulations of mobile satellite channel amplitude time series realizations, and can be combined with state transition models to provide a complete multi-state fading model.

“…Such an abstract scenario can be specialized to a particular application simply by choosing an appropriate channel model. For example, mobile satellite services (MSS) in the L-and S-bands require the channel described in [20] and [21], whereas in the Ka-band the channel model can be the one proposed in [22] and [23]. Without loss of generality, we assume the polarizations to be circular, and left-hand (LH) or right-hand (RH) oriented.…”

Abstract-In this paper, we investigate the performance of constellations optimized for transmissions in dual-polar mobile satellite applications. These four-dimensional constellations (inphase and quadrature per polarization) are designed for joint transmission over the two polarizations. Such constellations enhance the reliability of the system by providing certain redundancy into their design. Their performance is compared with transmission of independent 2D constellations over each polarization. As performance metrics, the pragmatic achievable mutual information and the bit error rate have been considered. The gains serve to indicate the need to further investigate 4D constellation design and its application in dual-polar MIMO systems.
