Multi‐antenna diversity gain in terrestrial broadcasting receivers on vehicles: A coverage probability perspective

“…follows a chi-squared distribution whose cumulative density function (CDF) is 1 − Γ (N, z) ∕Γ (N) ; Γ(s) = ∫ ∞ 0 t s − 1 exp( − t)dt and Γ(s, z) = ∫ ∞ z t s − 1 p( − t)dt denote the gamma function and upper incomplete gamma function, respectively. Owing to the alternative expressions of the gamma functions, (2) are rewritten as which is a better and more tractable form than (2). As a corollary, the counterpart for SR is given in a reduced form as A coverage probability is in essence a complementary CDF of the aggregate small-scale fading gain.…”

“…A 1080p FHD video was conveyed in the transmission, and the transmission configured by Table 1 was physically capable of delivering 7.79 Mbps and had a It can be graphically found in Figure 8 that the MR substantially reduces the reception failures in mobile environments. 2 For the sake of clarity, each of the reception success and failure points is indicated by green and black markers, respectively. Focusing on the north side of the subfigures, which was the furthest area from the Tx within the test route and was also shadowed by terrain features, the use of additional receive antennas explicitly converted more reception failure points into reception success points.…”

“…Motivated by the recent advances in self-driving technologies, infrastructure-to-vehicle (X2V) data delivery has attracted significant attention from both industry and academia. The contribution of the Media and Entertainment (M&E) vertical has appeared especially notable because a progressive evolution in driving-time activities is expected in the near future [1][2][3]. According to increasing demand for high-quality content and immersive meta-services, mobile broadcasting has been rediscovered to be a key momentum for such multimedia-invehicle movement, owing to the excellent point-to-multipoint (PTM) efficiency of terrestrial broadcasting [4][5][6][7][8][9][10].…”

DASH Live Broadcast Traffic Model: A Time-Bound Delay Model for IP-Based Digital Terrestrial Broadcasting Systems

“…The paper [12] focuses on an experimental model that creates 8K UHD contents and measures the transmission delay in the wired network path length of about 600 km. The paper [13] focuses on actual implementation and field tests in IP-based convergence of terrestrial broadcast and broadband networks using ATSC 3.0 standard. When a receiver cannot find a segment with a (t + 1) over broadcast, it will be able to request and receive the segment with (t + 1) over broadband.…”

“…When a receiver cannot find a segment with a (t + 1) over broadcast, it will be able to request and receive the segment with (t + 1) over broadband. Based on the real test in the paper [13], another study investigates the reliability gain of broadcast and broadband cooperation [14]. It describes the system models of broadcast and broadband networks as well as the delivery failure performance of cooperative over broadcast and broadband networks.…”
