摘要： A system for broadcasting and receiving a beacon signal includes a beacon transmitter (210, 400) and a beacon receiver (320, 500). The beacon transmitter includes a beacon signal generator (410) to generate a beacon signal, and a directional antenna system (420) to selectively transmit the beacon signal in a corresponding one of M different directions during each one of M beacon slots (342) during a beacon period (340) in each of a plurality of superframes (330). The beacon receiver includes a beacon signal detector (510) to receive and detect the beacon signal, and a directional antenna system (520) having an antenna pattern including a main lobe and being adapted to selectively steer the main lobe in a selected one of N different directions during each of a plurality of receiver frames each having a time period substantially equal to a time period of one of the superframes.

摘要： A wireless device (A) in a first antenna sector (40) is discovered using a directional antenna (322), which sends and receives signals in multiple antenna sectors. Multiple primary beacons are transmitted in corresponding primary beacon time slots (1P - 4P), which correspond to the antenna sectors (10 - 40) and have associated secondary beacon time slots (1s - 4s). A secondary beacon is received from the wireless device in a first secondary beacon time slot (4sA) associated with a first primary beacon time slot (4P) corresponding to the first sector, the secondary beacon being responsive to a first primary beacon included in the first primary beacon time slot. An additional first secondary beacon time slot (4s) is added in association with the first primary beacon time slot. The additional first secondary beacon time slot enables an additional wireless device in the first sector to send an additional secondary beacon in response to a subsequent first primary beacon included in the first primary beacon time slot.

摘要： The system (800), transmitter (600), receiver (700), and method of the present invention provide a technique to reduce the Peak to Average Power Ratio (PAPR) for the single carrier and single carrier block transmission (SCBT) modulations, especially when non-symmetric constellations (e.g. BPSK) are used. The constellation used for the modulation of each symbol, is rotated by a phase. Only the constellation is rotated, and the mapping of the bits into each constellation may or may not be similar. Further, in alternative embodiments the modulated bits are either encoded or not encoded. In a further alternative embodiment, a Trellis Coded Modulation (TCM) is used. Because the phase rotation is known a priori, or can be determined from a priori known information, it can easily be corrected at the receiver.
摘要翻译：本发明的系统（800），发射机（600），接收机（700）和方法提供了降低单载波和单载波块传输（SCBT）调制的峰均功率比（PAPR）的技术，特别是当使用非对称星座（例如BPSK）时。用于每个符号的调制的星座旋转相位。只有星座旋转，并且位到每个星座的映射可以是或者可能不相似。此外，在替代实施例中，调制比特被编码或不被编码。在另一替代实施例中，使用网格编码调制（TCM）。因为相位旋转是先验已知的，或者可以从先验已知信息确定，所以可以容易地在接收机处校正相位旋转。
