Nowadays more and more TV terminal devices for digital terrestrial broadcast are also equipped with broadband network interfaces. In view of this fact, we developed a novel redundancy on demand (RoD) system to improve the reception of terrestrial broadcast signals with the help of additional redundancy data transmitted via broadband networks. We propose various forms of redundancy, which can be provided on request by the receiving terminal in case of reception errors. RoD does not require any changes of the current broadcast network structure and is compatible with conventional receivers. Simulation results show that a small portion of additional redundancy data provided by the broadband network leads to significant performance improvements of the reception, making high data rate broadcasting feasible in a realistic environment. RoD introduces a new degree of freedom for network planning helping to reduce transmission cost and network energy consumption.

The basic idea of the "Tower Overlay over LTE-A + " system (TOoL + ) is to offload popular services, especially live video, from cellular networks, thereby decreasing the operational cost of such networks. This can be realized by using High Tower High Power (HTHP) transmitters whose signals can be seen as an overlay to the cellular networks. For the integration of HTHP signals into the cellular networks, the Carrier Aggregation (CA) mechanism known from LTE-A is used. Future Extension Frames (FEFs) provided by the terrestrial broadcast standard DVB-T2 are used to generate a time-division multiplex of signals according to either DVB-T2 or LTE-A. This approach provides a backward compatible migration path from classical TV broadcast to TOoL + as well as co-operative spectrum usage and the reuse of existing transmitter sites. After introducing the proposed system, this paper presents a demonstrator to show the technical feasibility of the concept. This demonstrator is based on the flexible Software Defined Radio (SDR) approach and covers both a Hybrid Modulator, an unmodified TV set and a prototype of an LTE-A + terminal.

“…Therefore, we extended our C++ SDR toolkit [3] by a generic framework enabling an automatic evaluation of these parameters by using different performance metrics such as execution time, clock cycles per instruction or cache misses. Existing frameworks focus either on a single selected metric, usually execution time, and/or are very inflexible and hard to use [4].…”

The usage of Software Defined Radio (SDR) even in Consumer Electronics (CE) devices is becoming more and more important because it provides high flexibility and reconfigurability. Although a real-time SDR implementation even of state of the art systems such as LTE-A+ or DVB-T2 using General Purpose Processors (GPPs) is possible, the performance of SDR applications is still an interesting research topic. Therefore, we developed a generic C++ based framework for evaluating the performance of these applications. The framework supports different metrics for different kinds of analysis, e. g. time, clock cycles per instruction or data throughput. These metrics can be used for the evaluation and comparison of different implementations of typical SDR algorithms such as Turbo Decoding, Fast Fourier Transformation, or Quadrature Amplitude Demodulation. Furthermore, it is shown how an SDR application can use this framework to automatically determine and use the best available implementation of an algorithm on a given platform, e. g. the fastest or the most energy-efficient implementation.
