We present a faster distributed broadcasting primitive for the classical radio network model. The most basic distributed radio network broadcasting primitive called Decay dates back to a PODC’87 result of Bar-Yehuda, Goldreich, and Itai. In any radio network with some informed source nodes, running Decay for O(d logn+ log n) rounds informs all nodes at most d hops away from a source with high p...

Orthogonal frequency division multiplexing (OFDM) has been an effective technique to combat multipath fading in wireless communications. It has been successfully used for HF radio applications and has been chosen as the standard for digital audio broadcasting and digital terrestrial TV broadcasting in Europe and high-speed wireless local areas networks. In this paper an overview of a multiple c...

The unstructured multi-hop radio network model, with asynchronous wake-up, no collision detection and little knowledge on the network topology, is proposed for capturing the particularly harsh characteristics of initially deployed wireless ad hoc and sensor networks. In this paper, assuming such a practical model, we study a fundamental problem of both theoretical and practical interests—the lo...

In the following paper the perspectives of spatial development of digital broadcasting in Slovenia will be presented. Digital broadcasting will be considered in two main streams – digital audio broadcasting and digital video broadcasting, both in the terrestrial mode. In the field of digital radio, T-DAB frequency block allotments were already coordinated at the Wiesbaden planning conference in...

We propose a PC-based real-time software Digital Video Broadcasting-Terrestrial (DVB-T) receiver, including hardware, driver, and software parts. The total data rate of DVB-T is much greater than that of Digital Audio Broadcasting (DAB). A more efficient signal processing algorithm than our previous software DAB receiver is necessary to improve the speed of the software part of the DVB-T receiv...

Telecommunication and broadcasting systems using radio-relay/base stations on board the high altitude platforms are expected to create the largest business market among its possible applications. Telecommunications Advanced Organization (TAO) and Communications Research Laboratory (CRL) is conducting R&D on the telecom and broadcasting system to demonstrate its feasibility. Prototype onboard eq...
