Spatial Variation of Digital Television Signal in an Indoor Environment

This paper describes the equipment used and the procedures adopted for the measurement of received signals and other quality of service (QOS) parameters from a single transmitter in two identical unoccupied apartments situated at the third and fifth levels above the ground. The spatial variations of the received signal in the apartments have been analyzed and the main results presented. The behaviour of other parameters will be briefly discussed and would be presented in more details in later papers. The objective of this study is to refine the measurement procedures, which will be used later to characterize the received signal (and other QOS parameters) in different indoor environments in the dense urban Housing Development Board (HDB) environments in Singapore. The results will be used for the planning of the future fixed digital TV service in Singapore.
