“…WiB builds on the earlier work of Cloud Transmission by Wu et al (1), and is radically different from conventional DTT and offers very attractive characteristics. In a traditional High Power High Tower (HPHT) DTT Multi-Frequency Network (MFN) or Single Frequency Network (SFN), a high capacity is typically transmitted per UHF channel, e.g.…”

A new system concept for DTT, called "WiB", is presented, where potentially all frequencies within the Ultra High Frequency (UHF) band are used on all transmitter (TX) sites (i.e. reuse-1). The interference, especially from neighbouring transmitters operating on the same frequency while transmitting different information, is handled by a combination of a robust transmission mode, directional discrimination of the receiving antenna and interference cancellation methods. With this approach, DTT may be transmitted as a single wideband signal, covering potentially the entire UHF band, from a single wideband transmitter via the TX site. Thanks to a higher spectrum, utilisation, the approach allows for a dramatic reduction in fundamental power/cost and approximately a 37-60% capacity increase for the same coverage as with current DTT. High speed mobile reception as well as fine granularity local services would also be supported, without any loss of capacity. The paper also outlines further possible developments of WiB, e.g. doubling the capacity via cross-polar Multiple In Multiple Out (MIMO), backward-compatible with existing receiving antennas, and adding a second, WiB-mobile, Layer Division Multiplexing (LDM) layer within the same spectrum, either as a mobile broadcast or as a mobile broadband.

Abstract-This review discusses the ISDB-TB and ATSC 3.0 systems, comparing the differences between the Input Formatting, passing by video compression, data multiplexing and encapsulation, the Channel coding, Interleavers, Constellation Mappers, Multiplexing methods, Framing, Waveform generation and synchronism. Finally, a performance comparison, using similar parameters, between bitrate and required Carrier-to-Noise ratio is presented. Index Terms-Digital

Abstract-This paper presents the design and simulations of a dual-polarized indoor antenna to receive the signal provided by the traditional ISDB-T system, operating in Ultra-High Frequency range destined to the radio-frequency channels after analog switch-off. The design goals were towards low cost, simple construction and implementation computational for indoor applications and with good performance in terms return loss within the frequency band. The antenna was designed and optimized using a full wave electromagnetic solver, and the results indicated that the proposed antenna has a good performance, simple structure and is a suitable candidate to be employed in the current digital television standard as in the nextgeneration of digital broadcasting.Index Terms-dual-polarized antenna, indoor antenna, integrated services digital broadcasting terrestrial (ISDB-T), MWS-CST Studio.
