Abstract

Diversity schemes are being used on mobile cellular networks to combat the effect of multipath fading mainly at the base station site. Since digital TV will be deployed using UHF bands, this paper proposes to study the feasibility of using space diversity for the mobile digital TV reception since these kind of system is also subjected to multipath effects. This work experimentally investigates the use of space diversity at the mobile digital TV terminal in order to quantify the real benefit this scheme can provide to digital TV reception when mobility is present. The gain results are presented in dB related to the 10% multipath fading probability occurrence improvement.
