    摘要: There is provided a wireless audio transmission system, in particular a wireless microphone system, for wireless audio transmission. The system has at least one wireless microphone unit for detecting audio signals and for wirelessly transmitting the detected audio signals, and a central unit. The central unit has a wireless receiving unit for receiving the wirelessly transmitted audio signals from the wireless microphone units, a pilot tone transmitting unit for transmitting a first pilot tone on a pilot channel, and a pilot tone receiving unit for receiving and processing a second pilot tone signal. The pilot tone signal has information in respect of the wireless transmission between the microphone units and the central unit.

    摘要: An audio transmission system including a wireless digital microphone unit which detects audio signals and wirelessly transmits the detected audio signals based on adjustable transmission settings and transmission parameters, and a central unit. The central unit has a monitor unit for monitoring and analyzing a frequency spectrum of an available frequency band, a link adaptation unit which adapts the microphone's transmission settings and parameters based on the results of the monitor unit, and a transmitting/receiving unit for receiving wirelessly transmitted audio signals from the wireless microphone unit and for transmitting transmission settings and transmission parameters via a return channel to the wireless microphone unit. The microphone's transmission settings and parameters are modified based on the transmission settings and transmission parameters transmitted via the return channel, which have a center frequency of a channel, a selection of a modulation method and parameters thereof, a data rate, and/or a channel encoding.

    摘要: An approach is provided for automatic geo-location and social group indexing thereby search geo-locations. A geo-location search learning platform receives a query specifying words, and retrieves context information of a user based upon a criterion. The geo-location search learning platform then assigns to the user a social group identifier identifying a social group based on the context information, retrieves one or more social group indexes based upon the social group identifier, retrieves one or more geo-location indexes based upon the one or more social group indexes, and generates a search result using, in response to the query, the one or more geo-location indexes and the words.
