摘要: A method and an apparatus for estimating a location of a terminal are provided. The method includes: receiving at least one base station signal from each of at least one base station; computing received signal information with respect to the received signal; and estimating the location of the terminal based on signal transmission direction information associated with the base station and the computed received signal information. The present invention can accurately estimate the location of the terminal based on directional information of base station signals.

摘要: In a network, a first network station (61) communicates with a second network station (65) using a first channel (45) from a plurality of channels. The first channel (45) has a central frequency (46). A third network station (62) communicates using a sub-channel (55) of the first channel (45). The sub-channel overlaps the first channel (45). The sub-channel (55) has a center frequency (56) that varies sufficiently from the center frequency (46) of the first channel (45) so that the first network station (61) and the second network station (65) do not lock onto packets transmitted from the third network station (62). The center frequency (56) of the sub-channel (55) is closer in frequency to the center frequency (46) of the first channel (45) than to a center frequency of any other channel in the plurality of channels.

摘要: A data flow from a source to a destination is routed in a multi-hop wireless network. Nodes are searched in the multi-hop wireless network for information of route metrics for the nodes, the information of the route metrics are received, a route that has a most optimal route metric for the data flow are determined based on the route metrics and a data flow metric of the data flow, and the data flow are received from the source via the route at the destination in the multi-hop wireless network.

摘要: Topology input is used to identify a set of data flows as between a set of virtual machines (VMs), as well as one or more network services for one or more of the data flows. A determination is made as to a minimal number of network service virtual machines (NSVMs) for use in providing the one or more network services. An arrangement is determined for server resources and network resources of the data center network on which a virtual network topology is provided for the tenant, including the set of VMs and the number of NSVMs.

摘要: A hybrid platform for a software defined radio (SDR) includes a receive/transmit antenna, a radio frequency (RF) frontend, a baseband processor, and a SDR positioned along a signal path that couples the antenna, the RF frontend, and the baseband processor. The SDR includes a transmit processing chain, a receive processing chain, and a FPGA that includes control logic to reduce distortion caused by signal transmission within the SDR.
