نویسندگان
چکیده
In this paper the basic principles for the design and implementation of a wide-band statistical model for the LMS (land mobile satellite) channel at various frequency bands are presented. The model is valid for different services including communications, broadcast, navigation, etc. The simulator implementing the model is suitable of the study of new systems, including those using LEO and other non-GEO orbits.

Statistical modeling of the LMS channel
In this paper, a statistical model for the land mobile satellite (LMS) channel is presented. The model is capable of describing both narrowand wide-band conditions. Other relevant characteristic is that it can be used to study links with geostationary as well as nongeostationary satellites. The model is of the generative type, i.e., it is capable of producing time series of a large number of si...
متن کاملTracking performance of incremental LMS algorithm over adaptive distributed sensor networks
in this paper we focus on the tracking performance of incremental adaptive LMS algorithm in an adaptive network. For this reason we consider the unknown weight vector to be a time varying sequence. First we analyze the performance of network in tracking a time varying weight vector and then we explain the estimation of Rayleigh fading channel through a random walk model. Closed form relations a...

This paper presents a low loss and high selective lowpass filter which is implemented using suspended stripline (SSL) technology. The proposed structure is comprised of a 13th order generalized Chebyshev lowpass filter which enjoys integrated waveguide-to-SSL transitions. This filter is designed and fabricated to be used as lowpass channel of a U-band diplexer employed in frontend of a U-band d...
متن کاملImage-based State Modeling of the Land Mobile Satellite Channel for Multi-satellite Reception
This paper investigates the image-based characterization of the land mobile satellite (LMS) channel. For a comprehensive multi-satellite model, a traditional measurementbased approach is not feasible due to the lack of available satellites at all possible orbital positions and the drawbacks of the measurement system when a high gain tracking antenna is involved (e.g. Ka/Ku band). To overcome th...
متن کاملEffects of the Channel Length on the Nanoscale Field Effect Diode Performance
Field Effect Diode (FED)s are interesting device in providing the higherON-state current and lower OFF–state current in comparison with SOI-MOSFETstructures with similar dimensions. The impact of channel length and band-to-bandtunneling (BTBT) on the OFF-state current of the side contacted FED (S-FED) has beeninvestigated in this paper. To find the lowest effective channel length, this device i...
