- Layered-Division-Multiplexing (LDM) technology has been shown to provide significant performance improvent for digital TV (DTV) broadcasting systems to simultaneously deliver a robust mobile TV service and one or more high-throughput fixed services in the same 6 MHz TV channel. So far, the focus of LDM for future DTV systems has been put on delivering mixed mobile and fixed services since this is one of the most interesting scenarios for broadcasters. However, the potential of using LDM to deliver multiple mobile services in the different layers has not been investigated and compared to their Time-Division-Multiplexing and Frequency-Division-Multiplexing (TDM/FDM) counterparts. In addition, for the typical mixed-service delivery mode, the fixed services delivered in the lower-layer (LL) are also available to mobile receivers having favorable reception conditions. It would be interesting to identify the actual availability of these services to different type of mobile receivers. In this paper, we first investigate the performance of using both layers of an LDM system to deliver multiple mobile services. Next, we investigate the availability of the high-throughput fixed services delivered in the LDM-LL to mobile receivers, and a potential technology to make these services more accessible.
