摘要： In a wireless transmitter having a plurality of spatial streams differentiable at a receiver, wherein data is encoded and transmitted over a communication channel with pilot tones to provide the receiver with information about the effects of the communication channel on the spatial streams transmitted, the benefits can be provided by identifying a plurality of symbol periods within which symbols representing some of the encoded data are to be transmitted, identifying pilot tone values for the plurality of symbol periods, wherein the identified pilot tone values are such that the receiver, when receiving at least some of the pilot tones having the identified pilot tone values, is provided with signals enabling the receiver to characterize the communication channel to obtain transmit stream diversity gain, and transmitting the symbols and the pilot tones over the plurality of spatial streams for the plurality of symbol periods. In some embodiments, the pilot tones are orthogonal over space and time or over space and time and frequency, while in others they are semi-orthogonal. Pilot tone values might be of a constant amplitude and phase shifted, or might also have amplitude variations wherein at least two pilot tones are nonzero for spatial streams for a given symbol period.

摘要： A modified preamble is used by extended devices that operate in mixed mode environments and green field environments, to accommodate beamforming of transmissions. In one process, an extended wireless device processes data for transmission of that data as a packet, wherein the extended wireless device is a device configured to communicate using a standard protocol understood by each node device and an extended protocol not understood by legacy node devices. If the packet is to be directed at an extended device, the extended wireless device sends a preamble of that packet that is usable in an extended mode at extended devices and usable at a receiving legacy device to determine that the receiving legacy device is not the destination of data to follow the preamble. Once the receiving legacy device is expected to be deferring the network, the extended wireless device can beamform its signal or otherwise vary from the legacy protocol in communications with extended devices.

摘要： A modified preamble (fig. 9B) is used by extended devices that operate at higher rates. 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 and provides some level of coexistence with legacy IEEE 802.11a devices.
摘要翻译：经修改的前导码（图9B）由以较高速率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/或扩展模式并提供与传统IEEE 802.11a设备的一些级别共存的属性。

摘要： Systems and methodologies are described that facilitate mitigating ringing effects of a voltage-controlled oscillator upon turning on a transmitter. A receiver generates at least one frequency offset estimate subsequent to an antecedent frequency offset estimate that is potentially erroneous due to ringing effects. The receiver extrapolates a phase error on upcoming symbols based upon a delta between the subsequent and antecedent frequency offset estimates. The phase error is employed to correct the upcoming symbol for ringing effects. In addition, the transmitter can detect a packet in advance of being ready for transmission and power up upon detection to allow the ringing to settle.
