Abstract EN
The rapid development of high-speed train and Metro communications has provided new challenges for the application of MIMO technologies.
Therefore, we propose a three-dimensional (3D) multiple-input multiple-output (MIMO) channel model using leaky coaxial cable (LCX) in a rectangular tunnel.
The channel model is based on geometry-based single-bounce (GBSB) channel model and the electric field distribution of LCX in the tunnel environment.
The theoretical expressions of channel impulse response (CIR) and space-time correlation function (CF) are also derived and analyzed.
The CFs for different model parameters (moving velocity and moving time) and different regions of the tunnel are simulated by Monte Carlo method to verify the theoretical derivation at 1.8 GHz.
In the same parametric configuration of nonstationary tunnel scenarios, the time delay of the first minimum value of CFs for LCX-MIMO is 1/5 of the time delay of the minimum value of CFs for dipole antennas MIMO when the train moving velocity is 360 km/h.
It is shown that, for MIMO system, the performance of using LCXs is better than using dipole antennas.
