Guidelines & Template

We are seeking original, novel, unpublished research/analysis that is not overtly commercial in tone and provides solutions to current challenges faced by our industry or gives insight into its future direction.

• Substantially New Paper: Proposals which have already been published or presented elsewhere will not be accepted.
• Written in English: Proposals must be written in English language. It’s a good idea to prepare your text off-line in a Word document before cutting and pasting it into the website template.
• Good Spoken English: Should your paper be selected for inclusion and presentation, the delivering speaker must be sufficiently proficient in verbal English language, to answer questions from the audience.
• Clear and Concise: Describe the advance or concept that will be the key topic of your paper highlighting what is unique, showing how it will improve existing systems or practices and explaining its background.
• Length: Synopses should typically be no more than 300 words in length. 
• Historical Papers: Offers of reviews or historical papers will only be accepted if they draw strong and relevant conclusions about future directions.
• Include Results: If the proposal describes experimental work, mention what the results (or anticipated results) show and explain what the impact might be.
• No Sales Pitches: Products or service pitches will not be accepted, however contributions explaining the use of technology in products or services may be considered.
• Demonstrations: If you intend to use tools such as simulations, demonstrations or 3D graphics to help an audience understand your presentation then please say so.

Title: WiB - Lower cost and higher performance for DTT using wideband 1-reuse 

Description: Current frequency planning of DTT is based on frequency reuse (also with SFNs). On a particular transmission site only a fraction of the available spectrum is actually used, which unfortunately is far from power efficient. The paper will present a new DTT system approach, where potentially all frequencies within the UHF band are used on all TX sites (reuse factor one). Interference is handled by a combination of a robust transmission mode, the directional discrimination of the receiving antenna (roof-top reception) and interference cancellation methods. This approach allows for a fundamental power saving of about 90% for the same coverage and total capacity (about 200 Mbps per site within 470-694 MHz) as with a “roof-top DVB-T2-only case”. 

In addition, high speed mobile reception as well as local services would be supported, without loss of capacity. With this approach DTT may be transmitted as a single wideband signal from a single wideband transmitter (per TX site), allowing RF combiners to be avoided. The system may also more easily allow positioning of the TX at the top of the mast, thereby also eliminating the need of the long RF feeder. A large reduction of CAPEX and OPEX for DTT is expected thanks to a range of factors, which will be presented in the paper. TFS frequency hopping would allow the receiver to use a smaller tuner bandwidth to extract a selected service, while keeping the full UHF band frequency diversity and statmux efficiency advantage. Unlike earlier MIMO proposals for DTT this approach would also allow MIMO to be introduced in a backward-compatible way with respect to existing antenna installations, using independently modulated streams, thereby doubling the total capacity. The paper will also include performance simulation results related to e.g. interference cancellation and coverage.
