Abstract :
We investigate the effects of reflective (metallic) insulation on indoor digital television (DTV) signal reception in rural houses. Simulation results indicate that under non-line-of-sight (NLOS) conditions, the presence of reflective insulation may significantly degrade indoor signal reception and cause a large variation of signal level inside a house. To predict the average signal level in domestic indoor sites, a simple empirical model that covers the DTV broadcast frequencies is proposed. Simulations also show that directional antennas may not necessarily improve indoor DTV signal reception.
