Abstract: Broadcast based information systems like Teletext use a unidirectional communication scheme in order to get access to information. This means that requests for data objects are not transmitted from a client to a server. Instead the receiver part of the client has to listen for the requested object on the broadcast medium and copy it to the local storage when it goes by. The access time from the receiver point of view is defined as the difference between the reception point in time of the object and the point in time when the request was made. Nowadays realized broadcast based information systems are not able to determine precisely when a requested object will be available. The present invention uses a repetition distance which defines an additional parameter which has to be transmitted with each broadcast data object at the transmitter side. The receiver can use this information to determine the precise repetition point in time of a requested object. This information can be used to realize a progress indicator, so that an user can be informed about the time he has to wait for the requested object. Also this information is essential for the realization of certain caching strategies.
Abstract translation: 基于广播的信息系统，如图文电视使用单向通信方案，以便获取信息。 这意味着对数据对象的请求不会从客户端发送到服务器。 相反，客户端的接收器部分必须在广播媒体上监听所请求的对象，并在它通过时将其复制到本地存储器。 从接收机观点来的接入时间被定义为对象的接收时间点与请求时间点之间的差。 现在实现基于广播的信息系统不能精确地确定所请求的对象何时可用。 本发明使用定义附加参数的重复距离，该附加参数必须在发射机侧与每个广播数据对象一起发送。 接收器可以使用该信息来确定请求对象的精确重复点的时间。 该信息可以用于实现进度指示符，使得用户可以被告知他必须等待所请求的对象的时间。 此外，这些信息对于实现某些缓存策略至关重要。

Abstract: A transmitting device, a receiving device, and a communication method for transmitting and receiving data modulated on frequency subcarriers of an OFDM communication system. An OFDM burst includes a preamble part and payload data part, whereby the preamble includes a section of pilot symbols mapped onto every n-th frequency subcarrier and signaling data mapped onto the frequency subcarriers between the frequency subcarriers with the pilot symbols. A first channel estimation on the basis of the received pilot symbols is performed, the result of which is used to reconstruct the entire section of the received preamble as a training pattern for an accurate channel estimation, which is used for a channel equalization of the received payload part.

Abstract: A radio transmission signal consisting of signal frames that comprise a dynamic data part and a quasi-static data part according to the present invention is characterized in that the dynamic data part of a respective frame contains an indicator showing in which following frame the quasi-static data part of this respective frame will be repeated. Therewith, an alternative frequency of e.g. a digital shortwave signal like a DRM signal can easily and satisfactorily be checked before a fast seamless switching to this alternative frequency can be performed. The inventive method to perform a seamless switching of a receiver from a first currently tuned frequency to a second alternative frequency is characterized by the step of receiving at least one set of samples from a respective signal transmitted on at least one second frequency during a time period during which said indicator assures that it is secure that only data that has been transmitted at least once is transmitted as signal on said first frequency to gather some information about said alternative frequency.

Abstract: The present invention refers to a method for defining useable frequency bands for a powerline communication (PLC) system (101) using power supply lines of a power supply network (104a) for interconnecting a number of PLC nodes (302, 306) such that electromagnetic emissions generated by PLC signals (s(t)) transmitted via said power supply lines do not interfere with broadcast RF signals radiated in the same frequency bands. Before starting own communication activities, PLC nodes (302, 306) participating in a PLC session scan (S1a) the entire frequency range designated for powerline communication to detect (S1b) frequency bands which are occupied by broadcast services. During powerline communication the occurrence of broadcast signals is regularly checked (S2) by screening (S2a) the entire frequency range designated for powerline communication and detecting (S2b) relevant broadcast bands that should be omitted during powerline communication to avoid interference noise (n(t)). After that, new frequency bands for powerline communication are allocated (S3) within said frequency range, provided that these new bands are not occupied by any detected wireless service.
