520 |a"Digital Radio Broadcasting (DRB) is a new L-band audio service that will replace existing AM and FM services in Canada starting in 1997; the CRTC has been accepting license applications since October 1995. Initial system roll-out is limited to terrestrial delivery, but future complementary satellite delivery will provide much more flexibility. In an effort to characterise the satellite channel for land mobile reception of DRB services, this document reviews existing literature that presents relevant propagation measurement results. A variety of reception conditions are considered, including mobile, portable, hand-held and fixed reception in open, rural, mountainous, wooded, suburban, urban and indoor environments. Fading statistics are presented according to these reception conditions, as well as elevation angle, presence of foliage and signal bandwidth. A summary of published propagation measurements is presented, including signal impairments and resulting fade mechanisms. The reviewed data indicates that the greatest cause of signal impairment is fading from tree shadowing, predominant in some rural and most suburban environments. Canadian authorities (government and industry) involved in DRB agree that urban and indoor reception will not be achieved via simple satellite delivery, and will require terrestrial on-channel repeaters to boost the signal strength. With this in mind, the results presented for urban and indoor reception are of less interest than results for other reception environments. This report also features a brief review of proposed propagation models, as well as a listing of various transmission platforms used in measurement campaigns and an exhaustive list of relevant references"--Executive summary.
