Abstract: Methods and apparatus for distributing documents are provided. A source node can determine a map for a document, where the map can include information about a number of portions of the document and a corresponding number of distribution nodes. The source node can, for each portion of the number of portions of the document, send the portion of the document to the corresponding distribution node. The source node can record, at a distributed storage system, a first transaction that records information related to the map for the document using the source node. The source node can determine to distribute the document. After determining to distribute the document, the source node can: record a second transaction related to a distribution identifier associated with the map for the document at the distributed storage system and can send a distribution notification that comprises the map for the document and the distribution identifier.

Abstract: Provided are a noise floor level reduction device and a noise floor level reduction method capable of reducing a noise floor level. A transmission power measurement system 10 is installed before a signal measurement device 20 including a noise floor level measurement unit 22 that measures a noise floor level, and a measurement unit 24 that subtracts the noise floor level from a level of a signal from a DUT 2 to calculate a level of a signal after subtraction, and includes an LNA 17 provided between the DUT 2 and the signal measurement device 20 for amplifying the signal from the DUT 2, and a termination resistor 16 that terminates an input of the LNA 17, and the termination resistor 16 terminates the input of the LNA 17 in a case in which the noise floor level measurement unit 22 measures the noise floor level.

Abstract: To provide a technique for simplifying a parameter setting process required to generate a test signal based on an LTE-Advanced system. Carrier arrangement designation means 25 displays a screen for selecting one of an intra-band type or an inter-band type as the arrangement of a plurality of component carriers used in an LTE-Advanced system such that one of the intra-band type or the inter-band type is designated. Parameter file designation means 26 designates a parameter file to be allocated to the component carrier among test signal generating parameter files stored in a parameter file storage means 24. Parameter and frequency band allocation means 27 designates the component carrier to which the designated parameter file can be allocated and the allocated frequency band for communication in which the component carriers are arranged.
