Investigations in Satellite MIMO Channel Modeling: Accent on Polarization
Due to the much different environment in satellite and terrestrial links, possibilities in and design of MIMO systems are rather different as well. After pointing out these differences and problems arising from them, two MIMO designs are shown rather well adapted to satellite link characteristics. Cooperative diversity seems to be applicable; its concept is briefly presented without a detailed ...
متن کاملMIMO Propagation Channel Modeling
This paper deals with MIMO propagation channel modeling which might be one of the important study areas realizing effective MIMO communication systems having higher channel capacities. After presenting basic propagation channel models both for narrowband and wideband signals, two recent propagation-related topics on MIMO system, i) MIMO utilizing dual and triple polarization diversity branches,...
متن کاملMIMO Channel Models for Satellite Communications
In recent years considerable attention has been drawn to the systems with multiple element transmitter and receiver arrays. It has been demonstrated both in theory and practice that multiple-input multiple-output (MIMO) systems offer the promise of increased capacity, high spectral efficiency and high gains by exploiting space-time processing techniques in particular space-time coding (STC) tec...
متن کاملSemi-Blind Channel Estimation based on subspace modeling for Multi-user Massive MIMO system
Channel estimation is an essential task to fully exploit the advantages of the massive MIMO systems. In this paper, we propose a semi-blind downlink channel estimation method for massive MIMO system. We suggest a new modeling for the channel matrix subspace. Based on the low-rankness property, we have prposed an algorithm to estimate the channel matrix subspace. In the next step, using o...
متن کاملSpatial Dynamic Wideband Modeling of the MIMO Satellite-to-Earth Channel
A novel MIMO (multiple input multiple output) satellite channel model that allows the generation of associated channel impulse response (CIR) time series depending on the movement profile of a land mobile terminal is presented in this paper. Based on high precise widebandmeasurements in L-band themodel reproduces the correlated shadowing andmultipath conditions in rich detail. Themodel includes...
