    • The invention relates to a disaggregation apparatus for determining electrical statuses of electrical consumers (2, 3, 4) in an electrical network (13). An overall electrical parameter, which is measured at least two different times and which is represented by a first number of sampled electrical parameter values, is used for determining a compressed difference overall electrical parameter, which is represented by a second number of sampled electrical parameter values being smaller than the first number. Compressed electrical signatures of the electrical consumers are provided, and the statuses of the electrical consumers are determined depending on the compressed difference overall electrical parameter and the compressed electrical signatures. Since compressed parameters and signatures are used for the disaggregation, less data have to be processed and have to be stored, thereby reducing the computational and storing efforts needed for the disaggregation.

    • DVB-T2 is the next generation standard for the terrestrial digital broadcast. There is the request of identifying the transmitters in the Single Frequency Networks mainly for testing purposes. This might be achieved by embedding a watermark sequence in the transmitters to identify them uniquely. However, the transmitters can also be deployed in SFN so they have to transmit exactly the same data. Therefore, the watermark has to be added at the radio signal. It connot be added at content level as it happens in other standard as, for instance, in cellular systems. The invention proposes two possible new methods to watermark the transmitter ID in the DVB-T2 signal. In both cases we assign orthogonal pilot sequences to different transmitters. In one case the sequences are added at very low power to ensure no loss in the data rate. This is a very attractive alternative, but it might require a much more expensive receiver. In the second case the sequences are added in a specific set of sub- carriers reserved for this specific use. This requires a better receiver synchronization and it also generates a small loss in data rate, but ensure a very simple and robust way to provide the transmitter identification.
    • DVB-T2是地面数字广播的下一代标准。 主要用于测试目的,要求在单频网络中识别发射机。 这可以通过在发射机中嵌入水印序列来识别它们来实现。 然而,发射机也可以部署在SFN中,因此它们必须传输完全相同的数据。 因此,必须在无线电信号处添加水印。 它包含在其他标准中发生的内容级别,例如在蜂窝系统中。 本发明提出了在DVB-T2信号中对发射机ID进行水印的两种可能的新方法。 在这两种情况下,我们将正交导频序列分配给不同的发射机。 在一种情况下,以非常低的功率添加序列,以确保数据速率没有损失。 这是一个非常有吸引力的选择,但它可能需要一个更昂贵的接收器。 在第二种情况下,将序列添加到为该特定用途保留的特定的一组子载波中。 这需要更好的接收机同步,并且还产生数据速率的小损失,但确保提供发射机识别的非常简单和鲁棒的方式。

    • The present invention relates to a data transmission network, in particular a single frequency network (SFN), comprising a space-time block code (STBC) encoder for encoding user data of a user data stream into channel symbols of two or more channel data streams for transmission and a plurality of transmitters in a transmission area for transmitting said channel data streams using the same frequency channel for reception by one or more receivers located in said transmission area, wherein the number of transmitters is larger than the number of channel data streams and wherein each channel data stream is transmitted by at least one transmitter. To enable the deployment of STBCs in an SFN and a uniform gain in the coverage area of the SFN the data transmission network further comprises control means for controlling, which channel data stream is transmitted by which transmitter, such that all channel data streams are simultaneously transmitted, that at least two transmitters are transmitting the same channel data stream and that at least one transmitter is changing which channel data stream it transmits.
