Study of digital TV signal reception in domestic indoor environment

Abstract

In this paper, indoor DTV signal reception has been investigated under four different circumstances. Simulation results show that both window location and the presence of conductor-backed insulation in a house could cause a more than 35 dB fluctuation in the signal-to-noise ratio presented to the DTV receiver. Although the effects from window location could be mitigated in the real world environment (because of multipath propagation), the presence of conductor-backed insulation could significantly degrade the signal reception inside the house. A more detailed investigation of indoor DTV signal reception, such as the incorporation of metallic water pipes and actual DTV antennas in the simulation, and field measurements is currently in progress.
