—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… (More)
A channel estimation algorithm for MIMO-OFDM systems in Fast Time-Varying Environments is proposed. The channel estimation function is based on the equivalent discrete-time channel taps or on the physical propagation channel parameters. To handle rapid variations of channels within a transmission block, we approximate the channel by a basis expansion model… (More)
The feasibility of an in-vehicle PLC, based on HomePlug standards is studied. The channel characteristics introduced in the simulation software are those deduced both from transfer function and noise measurement and from propagation modelling.
This paper investigates the propagation channel characteristics of a power line communication inside a vehicle. Transfer functions have been measured between various points of the DC network in a frequency range extending from 500 kHz up to 70 MHz to deduce the statistical behavior of the path loss, delay spread and coherence bandwidth. The results are… (More)
