摘要： Systems and methods for optimally receiving differential encoded OFDM signals via multiple antennas. These techniques may exploit spatial diversity without knowledge of channel characteristics. Further systems and methods are provided for exploiting frequency diversity within an OFDM burst where differentially encoded symbols are repeated to assure optimal performance. The output of differential decoding systems may also be used to provide soft decision values for individual bits of multibit symbols to facilitate use of bitwise channel decoding systems.

摘要： Systems and methods for communicating packets having a plurality of formats are described herein. In some aspects, a signal (SIG) field in the preamble of a packet may indicate whether an extension field, such as an extension SIG field or SIG-B field, is included in the packet. In another aspect, one or more detectors may be used to auto-detect packets formatted as one of at least two different formats based on a short training field (STF) of a received packet. In some aspects, along training field (LTF) in the preamble of a packet may indicate whether the payload is repetition coded.

摘要： A modified preamble is used by extended devices that operate at higher rates, MIMO or other extensions relative to strict 802.11a-compliant devices. The extended devices might use multiple antenna techniques (MIMO), where multiple data streams are multiplexed spatially and/or multi-channel techniques, where an extended transmitter transmits using more than one 802.11a channel at a time. Such extensions to IEEE 802.11a can exist in extended devices. The modified preamble is usable for signaling, to legacy devices as well as extended devices, to indicate capabilities and to cause legacy devices or extended devices to defer to other devices such that the common communication channel is not subject to unnecessary interference. The modified preamble is also usable for obtaining MIMO channel estimates and/or multi-channel estimates. The modified preamble preferably includes properties that facilitate detection of conventional and/or extended modes (“mode detection”) and provides some level of coexistence with legacy IEEE 802.11a devices.
摘要翻译：经修改的前同步码由相对于严格的符合802.11a标准的设备的较高速率，MIMO或其他扩展操作的扩展设备使用。扩展设备可能使用多个天线技术（MIMO），其中多个数据流在空间和/或多信道技术上复用，其中扩展发射机一次使用多于一个802.11a信道进行发射。 IEEE 802.11a的这种扩展可以存在于扩展设备中。经修改的前导码可用于对传统设备以及扩展设备进行信令，以指示能力并使遗留设备或扩展设备推迟到其他设备，使得公共通信信道不受不必要的干扰。经修改的前导码也可用于获得MIMO信道估计和/或多信道估计。修改的前导码优选地包括便于检测常规和/或扩展模式（“模式检测”）并且提供与传统IEEE 802.11a设备的一些级别共存的属性。

摘要： Circuits, methods, and apparatus that provide high-throughput control fields that, among other functions, provide efficient TXOP handoffs in wireless networks. A handoff may be made by setting one or more bits in a field in a QoS frame, such as the HT control or other appropriate field. Various conditions may be placed on a handoff by a granting station. For example, conditions specifying where a station receiving a TXOP handoff may send data, what the receiving station may do with any remaining TXOP, or what types of data may be transmitted by the receiving station may be imposed. These various conditions may be combined or omitted in any logic combination.

摘要： Improved beamforming techniques are provided for use in MIMO (multiple-input, multiple-output) communication systems, including MIMO-OFDM systems. The techniques include: (1) determining beamforming (BF) weights using a smoothed singular value decomposition (SVD) of the channel matrix; (2) determining BF weights using a power-optimized minimum mean-square error (MMSE) technique when the number of available transmit antennas exceeds the number of signal streams; and (3) determining BF weights using a hybrid SVD-MMSE technique. Additional techniques for reducing the impulse response length of the BF weights and/or normalizing the power per transmit antenna or per data stream may be used in conjunction with these or other beamforming techniques.
