Abstract
Nowadays metro plays an important role in people's daily life. It is significant to realize a high-data-rate wireless connectivity in metro carriages. In this paper, the intra-metro channels with the consideration of self-user shadowing at 28 GHz are characterized by ray-tracing (RT) simulation. The three-dimensional metro model is reconstructed according to the actual size of Madrid Metro. Based on the RT simulation results, totally six cases (three transmitter deployments, with and without self-user shadowing) are characterized in terms of angular spreads, received power, root-mean-square (RMS) delay spread. Once the user shadows the channel, the received power will be approximately 15-25 dB less than that of unoccupied. Compared with the parameters of angular spreads and RMS delay spread without shadowing, the wireless link is established by Non-LOS due to the self-user shadowing effect. These results provide valuable insights into the system design and evaluation for wireless communications inside the metro scenario.
