“…Further, this assumption allows to simulate the offloading cooperation scenario where the LTE broadcast mode (e.g. eMBMS) is improved and then embedded in DVB-T2 future extension frame as suggested in [3], [4].…”

“…As an example, a common physical layer with a flexible waveform is specified in [3] to provide a unified system suitable for mobile broadband and TV broadcast networks. Complementary to this, [4] proposes a cooperation scenario in which LTE broadcast services are offloaded to a DVB network using the concept of LTE carrier aggregation and DVB-T2 future extension frame. In these studies, as in many others dealing with network cooperation, investigations have been mainly focused on network selection decision and often assume a common coverage area for the mobile broadband and broadcast networks.…”

An exponential growth of the mobile data traffic is expected in future networks. The reason of this growth is related to the increasing popularity of linear services such as mobile TV, live and sports events, which may lead to the delivery of the same contents to a large audience. Recent studies have shown that network cooperation is a promising candidate to deal with such an issue. This paper investigates, from a planning perspective, the optimization of a hybrid unicast/broadcast network for linear services. We introduce an analytical approach with the aim of stating an optimization problem on the hybrid network configuration, namely in terms of the sharing between the unicast and broadcast modes to deliver a particular service. We show by simulation the existence of an optimal operation point which leads to the maximization of the overall throughput of the hybrid network under the constraint of a minimum service success rate.

Following the increasing growth in the demand on mobile TV, hybrid broadcast/broadband networks emerged as a suitable approach to overtake the challenges introduced by each network separately in order to enhance users' experience. This paper presents two possible scenarios for a hybrid, spatially separated, broadcast/broadband network to offer mobile TV linear services for the end users. Namely, the first scenario is based on shared spectrum access for both networks while the second one proposes a dedicated spectrum. Using a stochastic geometry approach, the paper derives analytical formulations for both the probability of coverage and ergodic capacity. These formulations are then used to optimize the hybrid network in terms of its key design parameters including the broadcast (BC) coverage radii, the broadband (BB) base stations' (BS) density, and spectral capacity. The results have shown that an optimal BC radius maximizing the probability of coverage and capacity exists and it depends on the BS density of the BB network. Other design parameters have been provided and analyzed leading to an optimal network deployment. To the best of the author's knowledge, this paper presents a first reference work dealing with the optimization of the hybrid network with the coexistence of broadband and broadcast networks, from stochastic geometry perspective, taking into account the inter-cell interference.

“…Therefore, an implementation benefits from the high flexibility and reconfigurability provided by Software Defined Radio (SDR). Additionally, using SDR it is easy to support several standards in parallel [1] thus reducing the number of hardware components and simplifying the overall CE design. Furthermore, SDR allows a fast and cheap implementation of prototypes showing new technologies live [2].…”

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.
