IBOC TECHNOLOGY:An Assessment of Technical & Operational Issues in the Canadian FM Radio Environment

http://www.cab-acr.ca/english/radio/dab/DRCG_Report_final.pdf

(Deals with FM IBOC, but there is a direct connection to AM IBOC by inference)

The Digital Radio Co-ordinating Group (DRCG) has prepared this report to assist broadcasters
and government regulators in assessing the technical & operational issues associated with
introducing in-band on-channel (IBOC) digital radio broadcasting (DRB) services in the
Canadian FM radio environment. Because it has been adopted as an IBOC standard by the US
FM radio industry, and equipment was therefore readily available, iBiquity Digital Corporation’s
HD RadioTM system was utilized in this evaluation.

The DRCG considers that, based on the evidence currently in hand, it would be risky for
Canadian broadcasters to proceed at this time with an unrestricted roll-out of HD Radio
services in the FM band, in the manner implemented in the US.
