摘要: A transmitter device includes a controller configured to generate a first field and a second field. The first field is at least one of a packet synchronization information field or a frame boundary indication field, the second field is a channel estimation field starting after the first field ends. The controller is configured to generate the second field at least in part by generating a first channel estimation sequence (CES) symbol and a second CES symbol. At least one of i) a sequence in the first field serves as a cyclic prefix of the first CES symbol, ii) a beginning portion of the second CES symbol serves as a cyclic postfix of the first CES symbol, or iii) an ending portion of the first CES symbol serves as a cyclic prefix of the second CES symbol.

摘要: Systems, methods, and other embodiments associated with preamble detection based on repeated preamble codes are described. According to one embodiment, an apparatus is provided that wirelessly receives a signal and calculates a differential output corresponding to a multiplication of the signal and a delayed version of the signal. A cross correlation is performed between the differential output and a known preamble pattern to produce a cross correlation output. A moving average calculation is performed on the cross correlation output to produce an average cross correlation. One or more peaks are detected in the average cross correlation when the average cross correlation has an amplitude greater than a threshold. When the one or more detected peaks meets predetermined criteria, the apparatus provides information about at least one of the detected peaks for subsequent signal processing.

摘要: A system, method, computer program and article of manufacture for updateable fan-out replication with reconfigurable master association in a large, multi-node LDAP environment. A replication ring supports the addition of fan-out nodes as children to each primary node that sits on a replication ring. The fan-out nodes can be cascaded in multiple parent/child relationships and can support full replication or a subset of the parent data. Each child/parent relationship is defined by an agreement. Each fan-out node replicates changes to their immediate children and parent based upon the change details and the configured agreement, distributing the replication load.

摘要: A rotary mechanism includes a base (10), a cover (30), a torsion spring (40) and a locking module (20). The rotary cover is rotatably mounted to the base. Two ends of the torsion spring are fixed with the base and the cover, respectively. The locking module limits the cover from rotating relative to the base. When the cover overcomes the limitation of the locking module, the cover can automatically rotate relative to the base due to the torsion spring.
