Design and Implementation of the DAB / DMB Transmitter Identification Information Decoder
نویسندگان
چکیده
The Transmitter Identification Information (TII) provides unambiguous identification of each transmitter in a Digital Audio Broadcast (DAB) and Digital Multimedia Broadcast (DMB) network. Recent researches showed that some useful services, such as location and automatic emergency alert, can be efficiently implemented with the assistance of TII. However many DAB/DMB receivers do not have the TII decoding functionality because the implementation of TII is optional in the standard. This has blocked the application of the new services. In this paper, the TII coding theory is analyzed and the design method of the TII decoder is reported. The proposed method can be either implemented in software, enabling the software-based DAB/DMB receivers to add TII decoding ability simply though firmware updating, or embedded in the hardware of a DAB/DMB baseband chip at a very low cost of only 286 logic elements and 1280 memory bits. Keywords—Digital Audio Broadcast (DAB), Digital Multimedia Broadcast (DMB), Transmitter Identification Information (TII), TII Decoder.
