Adoption of a System Standard for Digital Radio Broadcasting (DRB) in Canada

The purpose of this Notice is to propose the adoption of the EUREKA-147 (DAB) system for digital radio broadcasting in Canada in the band 1452-1492 Megahertz.

Digital compact disk and tape sound reproduction systems have led consumers to also expect very high quality sound from radio broadcasting systems. Although AM and FM broadcasting systems can provide adequate service to most stationary receivers, frequency congestion, multipath and interference are making it increasingly difficult to deliver high quality sound to mobile or portable receivers. In order to meet higher quality expectations, broadcasters around the world have decided that a new digital sound broadcasting system is needed. Such a system should be designed at the outset to meet enhanced quality as well as provide innovative features possible with digital techniques.

The 1992 World Administrative Radio Conference (WARC-92) allocated the frequency band 1452-1492 MHz on a world-wide basis to the terrestrial broadcasting service and the satellite-broadcasting service for the provision of digital radio broadcasting (DRB). Development work in Europe, which started in the eighties, resulted in the EUREKA-147 (DAB) system being adopted by the European Telecommunications Standard Institute (ETSI) as the ETS 300 401 Standard. This system has also been recommended world-wide for digital radio broadcasting by Sound Broadcasting Study Group 10 of the International Telecommunications Union. It's formal adoption by the Union for terrestrial and satellite DRB is expected in October.

EUREKA-147 (DAB) is a wideband system designed to provide high-quality digital radio broadcasting and data services to mobile, portable and fixed receivers at frequencies below 3 GHz. Field tests and demonstrations in Canada, Europe, Australia and other countries have shown the system to be highly spectrum and power-efficient for the provision of terrestrial DRB services in stationary and mobile environments. In Canada, extensive studies and field tests of the characteristics and performances of the EUREKA-147 (DAB) system were undertaken by industry and government experts over the past few years. Stations were established in Montreal and Toronto for experimentation and demonstration purposes. An industry/government task force on digital radio was established, and it provided comprehensive recommendations on a policy and licensing framework for its introduction into national service.

In addition, Canadian industry and government officials have cooperated with other countries in demonstrating the system, in exchanging technical information and carrying out joint studies.

All these activities have confirmed that the EUREKA-147 (DAB) system meets the needs of the Canadian broadcasting system for a high quality digital radio service. The broadcasting industry in Canada has endorsed this conclusion and has asked that the EUREKA-147 (DAB) system be adopted as the DRB standard for Canada in the 1452-1492 MHz band.

The intention is that AM and FM terrestrial broadcasting services will migrate to the new digital service over time. The data transmission capability of the digital service will make possible innovative enhancements to broadcasting. It is expected that the same system will be used for satellite DRB when the need arises for a complementary satellite/terrestrial service in the future.

The essential characteristics of the EUREKA-147 (DAB) system are described in the Revised Recommendation ITU-R BS 1114 Annex 1 (Digital System A) – Ref. ITU-R Document No. 10/21 dated December 12, 1994, ITU, Geneva. Copies of this document may be obtained from: Industry Canada, Publishing Services Centre, 300 Slater Street, Ottawa, Ontario, K1A 0C8, or from regional offices in Vancouver, Winnipeg, Toronto, Montreal and Moncton.

Interested parties may submit comments on this proposal to the Director General, Spectrum Engineering Branch, Department of Industry, 300 Slater Street, Ottawa, Ontario, K1A 0C8, or at the internet address

Comments should be submitted no later than 60 days from the date of publication of this notice. Comments received will be made available on written request to the Director General.

Dated at Ottawa this 28th day of July 1995.
