— Recently, Multimedia Broadcast Multicast Service (MBMS) has been specified by 3GPP as a Release 6 feature in order to meet the increasing demands of multimedia download and streaming applications in mobile scenarios. H.264, as the unique recommended video codec for MBMS, serves as an essential component because of its high compression efficiency and easy(More)
— In this work we address reliable file delivery over mobile broadcast networks, concentrating on the Raptor codes as specified for Multimedia Broadcast/Multicast Services (MBMS) within 3GPP. We start by describing Luby-Transform (LT) codes, which are the first practical fountain codes. Then, using a natural and easy to understand linear algebra notation,(More)
The performance of multiple-input multiple-output (MIMO) systems is greatly influenced by the spatial-temporal correlation properties of the underlying MIMO channels. This paper investigates the spatial-temporal correlation characteristics of the spatial channel model (SCM) in the Third Generation Partnership Project (3GPP) and the Kronecker-based(More)
—In this paper we investigate the time and frequency synchronization as well as the sector and cell search for the 3GPP Long Term Evolution (LTE) downlink. The proposed algorithms rely on the synchronization and cell-specific reference signals and are hence compliant to most recent 3GPP specifications. Time and (fractional) frequency offset coarse(More)
In typical parameter estimation problems, the signal observation is a function of the parameter set to be estimated as well as some background (environmental/system) parameters assumed known. The assumed background could differ from the true one, leading to biased estimates even at high signal-to-noise ratio (SNR). To analyze this background mismatch(More)
SUMMARY Rule-based modeling (RBM) is a powerful and increasingly popular approach to modeling intracellular biochemistry. Current interfaces for RBM are predominantly text-based and command-line driven. Better visual tools are needed to make RBM accessible to a broad range of users, to make specification of models less error prone and to improve workflows.(More)
Reliable transmission of video over wireless networks must address the limited bandwidth and the possibility of loss. When the bandwidth is insufficient on a single channel, the video can be partitioned over multiple channels with possibly unequal characteristics at the expense of more complex channel coding (error correction). This paper addresses the(More)
