摘要： A method and wireless device merge multiple unsynchronized beacon groups in a wireless network, each beacon group including at least one wireless device. A first beacon is received from at least one first wireless device in a first beacon group (S514), the first wireless device having a first directional antenna. A second beacon is received from at least one second wireless device in a second beacon group that is not synchronized with the first beacon group (S516), the second wireless device having a second directional antenna. A first response beacon is relocated (S520) and sent (S522) to the first wireless device in the first beacon group. The relocated first response beacon instructs the first wireless device to relocate the first beacon. Accordingly, the second beacon, the relocated first response beacon, and the relocated first beacon are synchronized.

摘要： A communication system includes first and second devices, where a processor of at least one of the first device and the second device is configured to establish a superframe having a superframe duration (Ts) and transmit a beacon by the first device during each of the superframe duration (Ts); scan by the second device all sectors (Nbeam) by scanning each sector for a superframe duration (Ts) and repeating a jump sequence. The jump sequence has a sequence duration (Ttotal) which is equal to a sum of a control duration (Tc) of a control channel and durations of data channels (KTd). The processor is further configured to find the first device by the second device during a find time (Tf), where the control duration (Tc) is greater than the durations of data channels (KTd).

摘要： An antenna (740) listens in each of a plurality of steerable sectors to determine if a primary beacon is present; transmits a primary device beacon in each of the plurality of steerable sectors if the primary beacon is not present; and transmits a secondary device beacon in a first one of the plurality of steerable sectors if a primary beacon is discovered. The antenna (740) may transmit the primary and secondary beacons on a different communication channel than a data communication channel or may transmit the primary and secondary beacons on a same communication channel as a data communication channel. The antenna (740) may divide the same communication channel into time slices wherein different time slices of a super-frame are utilized for the primary beacon, the secondary beacon, and the data communication. The secondary device (C, D) sends additional beacons in additional sectors if it receives non-primary beacon from the additional sectors.

摘要： A Single Carrier Block Transmission (SCBT) system employs an inherently parallel approach to error correction processing. At the transmission system (200), an incoming data stream is split (210) into P parallel data streams, each having a data rate equal to a fraction of the incoming data stream's data rate. The parallel data streams are then each separately encoded (220) in P parallel encoding processes (beneficially, using P parallel encoders (222)). The P separately encoded data streams are then merged (330), interleaved (320), and mapped (310) into a single stream of encoded symbols, which are transmitted to the receiver using an arbitrary modulation (240) and transmission scheme. At the receiver (255), the received data stream is de-interleaved (350) and split into P encoded data streams, which are then decoded (285) using P parallel decoders. Then, the decoded data streams are combined or multiplexed (295) into a single data stream.
