초록
In this paper, we present field test results of a layered division multiplexing (LDM) technology for the next generation digital television system, and analyze the results in several scenarios such as rooftop, indoor, and mobile receptions. In order to evaluate performance of the LDM technology, the field strength or the reception power is measured for all considered scenarios. Furthermore, the threshold of visibility, the marginal reception power, and the erroneous second ratio are measured for fixed, indoor, and mobile receptions, respectively. The field test results show that LDM technology enables broadcaster not only to efficiently provide a variety of services (e.g., mobile, indoor, and stationary services) with different robustness within a single radio frequency (RF) channel but also to increase flexible usage of the RF channel.
