Experimentally assessing the whole-body specific absorption rate (SAR(wb) ) in a complex indoor environment is very challenging. An experimental method based on room electromagnetics theory (accounting only the line-of-sight as specular path) is validated using numerical simulations with the finite-difference time-domain method. Furthermore, the method(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)
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)
