Modeling and Understanding MIMO Propagation in Tunnels
This paper first presents an application of the modal theory for interpreting experimental results of the electromagnetic field variation along a tunnel. The transmitting frequency is assumed to be high enough so that the tunnel behaves as an oversized waveguide. Then, for a Multiple-Input Multiple-Output channel, theoretical results of the channel capacity are given. To explain the decrease of...
متن کاملModeling of MIMO propagation in Tunnels
Wireless communication draws the attention of various and this is because, it increases in data throughput and also the link range without the increased transmit power or additional bandwidth. The explanation and/or prediction of the inside distribution field such tunnels are excited by the electric antenna which is essential for deployment of wireless communication system. Primary objective of...
متن کاملPropagation in Subway Tunnels: SISO and MIMO Channel Characterization
This paper first describes experimental results on the characterization of the propagation in subway tunnels. A first set of experiments have been carried out in Paris subway to determine the path loss, the long term and short term fading and the masking effect produced by a train. Then a wide band analysis has been performed both for a SISO (Single Input Single Output) and for a MIMO (Multiple...
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 کاملpassivity in waiting for godot and endgame: a psychoanalytic reading
this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
