Propagation in Subway Tunnels: SISO and MIMO Channel Characterization
نویسنده
چکیده
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 Input Multiple Output) transmission. The improvement of the channel capacity which can be expected with MIMO techniques is outlined. Key-Words :Propagation, MIMO, Tunnel, channel capacity

Theoretical and experimental analysis of the channel capacity enhancement based on MIMO techniques in subway tunnels
Both a theoretical approach and measurements of channel characteristics have been carried out to determine the maximum capacity which can be expected when MIMO techniques are implemented in tunnels, and especially in subway tunnels. The influence of the position of the antennas inside the transmitting and the receiving arrays on the correlation between paths and on the singular values of the tr...
متن کاملCharacterization of an Off-Body Channel at 2.45GHz in an Underground Mine Environment
Underground mines are challenging environments for off-body wireless communication, since the signal propagation is majorly affected by small scale and large scale fading. The use of multiple antennas at the transmitter and the receiver sides is a known technique to combat fading and enhance capacity. In this paper, the channel parameters of a 2 × 2 Multiple-Input MultipleOutput (MIMO) off-body...
متن کاملSingle-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

In this paper, an experimental characterization of a MIMO underground channel is presented. A simple statistical model is proposed at 2.45 GHz. The channel is characterized in terms of path loss, shadowing, RMS delay spread, and capacity. The measurements are carried out in an underground mine, which is a harsh confined environment. The path loss model is extracted from measured data for the li...
