摘要： Disclosed is a voice band splitting scrambler. To simplify the hardware thereof, the apparatus comprises a band splitting unit (11) for splitting an input voice signal into a plurality of band channels, and a scrambled voice signal generating unit (13) for carrying out spectrum-inverting and band-relocating operations on the respective channels to generate a scrambled voice signal. The scrambled voice signal generating unit (13) includes a modulating unit (15) for band-relocating the respective channels by noninverting carriers of inverting carriers set in different bands respectively; and an adding unit (17) for adding the signals of the noninverting channels and the signals of the inverted channels to each other.

摘要： A base station BS transmits downlink data to a relay station RS. A mobile station MS transmits uplink data to the relay station RS. The relay station RS determines a first modulation scheme for transmitting the uplink data to the base station BS, and determines a second modulation scheme for transmitting the downlink data to the mobile station MS. The relay station RS multiplies a symbol sequence obtained by the first modulation scheme by a symbol sequence obtained by the second modulation scheme for each symbol, and multicasts the multiplication result to the base station BS and the mobile station MS.

摘要： Node-B transmits a power profile of each frequency of transmission data as a step function to a UE. Each UE measures the amount of interference of a received signal, evaluates SINR over the entire frequency band with the power of the received signal, and transmits the evaluation result to Node-B. Node-B evaluates the interference profile in Node-B from the information about the SINR transmitted from the UE and the power of the transmission signal, and determines the frequency profile of the power of the signal transmitted to the UE.

摘要： In a telecommunication network, each node is provided with the same physical topology information relating to a physical construction of telecommunication paths included in the telecommunication network and with the same logical topology information relating to routing of telecommunication paths. When a failure occurs, restoration is effected by transmitting information relating to the failure that has occurred in the telecommunication network, throughout the network. Each node that receives the information relating to the failure determines alternative paths for bypassing the failure using the information relating to the failure, the physical topology information, and the logical topology information. Then service is switched to the alternative paths.

摘要： A path switching system and method for a multiple-node ATM network, in which a plurality of paths can be simultaneously switched preserving proper correspondence thereof. A key choosing unit provided in a node chooses first and second sorting keys out of the virtual paths between the nodes, based on a first and second path information stored in a path information memory unit. Two nodes located at both ends of the route failed due to trouble in the ATM network select a first pair of isolated virtual paths having the first sorting key, which were formerly connected to the failed route, and connect them to a first bypass route. The two nodes then connect in a similar way a second pair of isolated virtual paths both having the second sorting key to a second bypass route.
