A method includes transmitting, at a first time, a first transmission vector signal towards an antenna via a feeder cable connected to the antenna; receiving a first reflected vector signal, the first reflected vector signal being a reflection of the first transmission vector signal reflected from a point in the feeder cable; determining a first transformed transmission vector signal by performing a first vector forward transform on the first transmission vector signal; determining a first transformed reflected vector signal by performing a first vector forward transform on the first reflected vector signal; determining a first complex conjugate vector signal based on the first transmission vector signal and the first reflected vector signal; determining a first computed vector signal by performing a first vector inverse transform on the first complex conjugate vector signal; and determining a first sub-vector by performing a windowing function based on the first computed vector signal.
In certain embodiments, a macrocell base station (BS), such as an LSAS BS, estimates its backhaul channels with a small-cell BS (e.g., a relay or repeater) by averaging multiple instances of a received pilot signal repeatedly transmitted by the small-cell BS. Since the macrocell and small-cell BSs are stationary, averaging the received pilot signal transmissions over time results in the zero-temporal-mean time-dependent component of each backhaul channel as well as zero-temporal-mean noise and interference signals from other wireless nodes to substantially cancel out, enabling the macrocell BS to relatively infrequently estimate a relatively time-invariant, dominant component for each backhaul channel. The macrocell BS uses the estimated dominant components to generate user-data-based downlink transmissions to the small-cell BS. In this way, the processing to estimate channel state information (CSI) data for the backhaul channels is greatly reduced compared to conventional techniques.

In one embodiment, prior to similarity measure computation, concept expansion based on disjunctive normal form (DNF) decomposition and non-conventional reasoning is applied to an original ontology to generate an expanded ontology having the original concepts plus one or more pseudo concepts. As a result, the similarity measure computation can produce results that more accurately reflect a human point of view than convention techniques.

An optical routing scheme in which an optical network having a mesh topology is configured to route optical packets through an optical routing layout superimposable with the mesh topology, but having a star-like topology. Using this routing layout, the optical network can be configured to transport optical packets from respective ingress nodes, through the hub node located at the star center, to respective egress nodes in a manner that enables a data throughput that approaches the theoretical capacity. No special hardware is required for implementing the hub functionality, and any node of the optical network can be configured to serve as the hub node. The latter feature enables relatively straightforward optimization of the optical routing layout and transmission schedule, e.g., by changing the identity of the hub node and adjusting the transmission schedule at the ingress nodes to synchronize packet arrivals to the hub node.

Method and apparatus for portable index on a removable storage medium
Techniques for supporting a portable index include, in response to determining that a removable computer-readable storage medium is recently mounted on a particular drive having a particular drive identifier, determining a particular media identifier for the removable computer readable storage medium. Before harvesting metadata from each file of a set of one or more files on the removable computer-readable storage medium, it is determined whether a portable index file is stored on the removable computer-readable storage medium. The portable index file includes, for each file of the set, data that associates the media identifier (312) and a relative directory path (314) for one file of the set with metadata (316) for the one file. If the portable index file is stored, then an index is caused to be retrieved from the portable index file without harvesting metadata from each file of the set.
