Transmission Rate Enhancement Schemes for Digital Radio Mondiale Systems
In this paper, transmission rate enhancement schemes for DRM (Digital Radio Mondiale), which is a worldwide standard for digital AM and FM broadcasting in the AM and FM bands below 170 MHz, are presented and compared. The data rate of the legacy DRM system is supported up-to 186kbps with 16QAM and MLC (Multi-level Coding) at 100 kHz bandwidth. However, this rate is not sufficient to achieve new...
متن کاملInterleaving IBOC Signals for a Digital HD Radio Multiplex
With increased saturation of the VHF band II used for FM, few frequencies are available for new radio stations in many markets. This paper describes the benefits of using the In Band On Channel (IBOC) signal in an all-digital configuration to boost the number of effective audio services in the FM band. A new method of creating an all-digital IBOC signal configuration is described. Multiple inst...
متن کاملDRM+, a perfect complement to DAB/DAB+ in VHF band III
Technical investigations suggest that DRM+ is a suitable candidate for the transition from analogue FM to digital broadcasting in VHF band II (87.5 108.0 MHz) in Europe [2]. Unfortunately, there are mainly three major problems to solve: 1. VHF band II is historically defined for the use of analogue FM sound broadcasting, and, it is – as such – extensively used in Europe; 2. the lack of agreed c...
متن کاملOverview of the Technologies available for Digitalisation of Terrestrial Radio Broadcasting in Europe1
The FM band (87.5-108 MHz) is home to a large number of radio programmes, and is still the main means of radio broadcasting in Europe. However, the FM band is fully allocated and therefore cannot offer a basis for increased diversity in the radio broadcasting landscape, nor can it offer an increase in the coverage areas of the broadcasters already licensed. Local radio as well as community and ...
متن کاملDevelopment of Narrow-Band Digital Land Mobile Radio
A narrow-band digital land mobile system has been developed that operates in the frequency bands of 150 and 400MHz, which are commonly used by transportation-related companies, local government, and public-sector organizations— and are therefore very congested. The number of users that can be accommodated in these bands is almost doubled by reducing the channel separation to 6.25 kHz, about hal...
