Canadian digital terrestrial television system technical parameters

On November 8, 1997, Canada formally adopted the ATSC Digital Television St andard for terrestrial transmission [1] as defined in document A/53 of the Advanced Television Systems Committee of the USA [2] and as modified by the FCC document MM Docket No. 87-268 [3]. This paper will discuss the Canadia n digital terrestrial television system technical parameters for implementa tion and frequency planning: interference protection ratios, reference syst em parameters, and radio frequency emission masks, as well as their design methodology. First, the Canadian terrestrial DTV design guidelines are pres ented, followed by the introduction of DTV reference receiving system set u p and the parameter selection of the interference protection ratios. Last, the design methodology of the emission masks is discussed.
