摘要： In an example embodiment, there is disclosed a technique that enables a wireless device to achieve coexistence with an interfering source. The wireless device determines when interference is present and not present during a service period and reports the duration of interference free interval. At the end of an interference period, the wireless device can send a trigger signal indicating the start of an interference free interval to request data be sent to the wireless station until the expiration of the duration of the interference free interval. In particular embodiments, the signal sent by the wireless device can include an offset, for example a timing synchronization function (TSF) value, to indicate the end of the interference-free interval, perhaps computed so as allow for some clock drift.
摘要翻译： 在示例性实施例中，公开了一种能够使无线设备实现与干扰源共存的技术。 无线设备确定在服务期间何时存在和不存在干扰，并报告无干扰间隔的持续时间。 在干扰周期结束时，无线设备可以发送指示无干扰间隔的开始的触发信号，以请求发送到无线站的数据，直到无干扰间隔的持续时间期满。 在特定实施例中，由无线设备发送的信号可以包括偏移，例如定时同步功能（TSF）值，以指示无干扰间隔的结束，可能被计算以允许一些时钟漂移。

摘要： Multiple Input Multiple Output (MIMO) technology in conjunction with the IEEE 802.11 standard enables simultaneous communication of data packets to or from multiple users in the same frequency. Spatial divisional multiple access (SDMA) is thus provided. In this way, system capacity can be increased to an extent that depends on available antenna resources and the multipath characteristics of the communication channel. Doubling or quadrupling of network throughput can be achieved.

摘要： A method and apparatus are provided to enable a server to determine if a client connecting to the server is doing so by means of human user interaction, as opposed to an automated process. In order to authorize access to services, the option of determining user identity, such as by means of a graphical shared secret, is also provided. Three aspects are described: (i) image formation from an object model; (ii) presentation of image choices to a user, and (iii) user action. Image formation includes the creation of one or more categorized 2-dimensional images with object regions for each image automatically qualified. These one or more categorized images can be created by means of a Randomizable Image Generation Object for Human Recognition, comprised of (i) a 3-dimensional object model, (ii) a plurality of rendering threshold and constraint parameters, and (iii) categorization and qualitative metadata. The one or more 2-dimensional images are preferably transmitted to the user for authentication without the image metadata, which may be retained on the server. Related inquiry text can be sent when human user interaction is being determined and not user identity authentication.

摘要： The MAC layer of a wireless communication standard is modified to facilitate MIMO (multiple input multiple output) processing and thereby increase capacity and/or spectral efficiency. In one implementation, the IEEE 802.11a standard is modified in this way. A contention free period (CFP) is divided between MIMO communications and non-MIMO communications. An access point may maintain a list of nodes operating in MIMO mode and nodes operating in non-MIMO mode.

摘要： A discrete multitone stacked-carrier spread spectrum communication method is based on frequency domain spreading including multiplication of a baseband signal by a set of superimposed, or stacked, complex sinusoid carrier waves. In a preferred embodiment, the spreading involves energizing the bins of a large Fast Fourier transform (FFT). This provides a considerable savings in computational complexity for moderate output FFT sizes. Point-to-multipoint and multipoint-to-multipoint (nodeless) network topologies are possible. A code-nulling method is included for interference cancellation and enhanced signal separation by exploiting the spectral diversity of the various sources. The basic method may be extended to include multielement antenna array nulling methods for interference cancellation and enhanced signal separation using spatial separation. Such methods permit directive and retrodirective transmission systems that adapt or can be adapted to the radio environment. Such systems are compatible with bandwidth-on-demand and higher-order modulation formats and use advanced adaptation algorithms. In a specific embodiment the spectral and spatial components of the adaptive weights are calculated in a unified operation based on the mathematical analogy between the spectral and spatial descriptions of the airlink.
