This paper presents feasibility verification of the Advanced Television Systems Committee (ATSC) 3.0 MIMO system for 8K-UHD terrestrial broadcasting services. For a reliable performance evaluation, computer simulation, laboratory test, and field trial are conducted, and the tests' results are compared with the same performance metrics. Several physical layer configurations with various data rates from 63 Mbps to 113 Mbps are verified. The field trial results confirm that the ATSC 3.0 MIMO system can support data rates up to 113 Mbps within a 6 MHz bandwidth.

This paper theoretically and empirically explores the reliability gain that can be obtained by installing multiple antennas in on‐vehicle broadcasting receivers. Analytical derivations reveal that maximal‐ratio‐combining‐based diversity allows a multi‐antenna receiver (MR) to achieve significantly better coverage probability than a single‐antenna receiver (SR). In particular, the notable MR gains for low‐power reception and high‐throughput services are highlighted. We also discuss various aspects of mobile MRs, including geometric coverage, volume of the users served, and impact of receiver velocity. To examine the feasibility of MRs in the real world, extensive field experiments were conducted, particularly with on‐air ATSC 3.0 broadcast transmissions. Relying on the celebrated erroneous second ratio criterion, MRs with two and four antennas were verified to achieve notable reliability gains over SRs in practice. Furthermore, our results also prove that layered‐division multiplexing can cope better with receiver mobility than traditional time‐division multiplexing when multiple services are intended in the same radio frequency channel.

This paper presents an impact of cross-polarization discrimination (XPD) for the ATSC 3.0 MIMO system. Laboratory tests are carried out to analyze system performance with different XPD environments. The laboratory test results show that the ATSC 3.0 MIMO system can provide reliable system performance for XPD above 10 dB.

Advanced Television Systems Committee (ATSC) 3.0 standard has defined a transmitter carrier offset (TCO) insertion to avoid possible pilot contaminations at the coverage edge. Despite this adoption, the practical gain of ATSC 3.0 TCO has been less investigated so far. This paper verifies the advantage of TCO in multipath fading channel environments, particularly by using real hardware solutions. The laboratory tests specifically address the scenario with a single adjacent interferer and consider the Rayleigh fading channel with 20 multipath taps. Every measurement is obtained from a testbed with professional exciters and commercial receivers, which fully comply with ATSC 3.0 specifications. The measurement results explicitly show that inserting TCO is beneficial if an untrustworthy ATSC 3.0 signal coexists with the desired signal at the same radio band.

This paper presents the mobile performance of the diversity receiver in the ATSC 3.0 system through a field test. The field test shows the performance gain of the diversity receiver was significantly improved when the number of antennas used in the field test was increased.
