摘要： According to an approach for mitigating the effects of rogue WAPs in wireless local area networks, a determination is made of one or more clients that are communicating with a rogue WAP. For example, messages may be intercepted and examined to identify messages that are sent by or to rogue WAPs. Information that identifies the one or more clients is then extracted from the messages and stored in a client list. Communications between the one or more clients and the rogue WAP are then disrupted. Embodiments of the invention include, without limitation, disrupting communications using deauthentication and by spoofing Address Resolution Protocol (ARP) responses.

摘要： A multiple access wireless communications architecture provides selective, simultaneous communications with wireless devices located in different sections of a spatial area around a communications apparatus referred to as "sectors". This includes communications between wireless devices in a single sector, between wireless devices in different sectors and between wireless devices and a wired network or wireless backhaul network. The wireless communications architecture generally includes two or more wireless antenna arrangements that are each configured to provide communications with wireless devices located in a particular sector. Each wireless antenna arrangement is further configured to determine whether signals are being communicated on a communications channel before transmitting on the communications channel. This may be implemented, for example, using a carrier sense or energy detection mechanism.

摘要： An approach for processing data received from a communications channel that minimizes noise power and optimizes impulse response length to reduce interference, such as from inter-;symbol interference (ISI) and inter-channel interference (ICI), is disclosed. For example, finite impulse response (FIR) filtering may be used with FIR coefficients that are determined by optimizing a function of the impulse response length and the noise power. The impulse response length is optimized based on the communications channel transfer function to reduce interference. The noise power is minimized based on the noise covariance as determined using the total noise power density. The approach accounts for noise from a variety of interference sources besides ISI and ICI. The result is a superior equalizer for use in communications receivers employing orthogonal frequency division multiplexing or discrete multitone modulation in communications protocols employing Asymmetric Digital Subscriber Line, G.Lite and Very High Bit Rate DSL.
摘要翻译：公开了一种用于处理从通信信道接收的数据的方法，其最小化噪声功率并优化脉冲响应长度以减少诸如来自帧间干扰（ISI）和信道间干扰（ICI）的干扰。例如，有限脉冲响应（FIR）滤波可以与通过优化脉冲响应长度和噪声功率的函数确定的FIR系数一起使用。脉冲响应长度基于通信信道传递函数进行优化，以减少干扰。基于使用总噪声功率密度确定的噪声协方差，噪声功率被最小化。除ISI和ICI之外，该方法还涉及各种干扰源的噪声。结果是在采用非对称数字用户线，G.Lite和超高比特率DSL的通信协议中使用正交频分复用或离散多音调制的通信接收机中使用的优越均衡器。

摘要： A novel approach for selecting communications channels and participants with which to communicate based on channel performance and transferring management functions between participants in a communications arrangement is disclosed. According to one aspect of the invention, a particular channel is selected based on channel performance and channel identification data is provided to a participant that sends a response on a channel selected based on the channel identification data. According to another aspect of the invention, a particular participant is selected from a group of participants based on the performance of a particular channel. According to yet another aspect, an associate master participant is selected to assume responsibilities for functions assigned to the master participant if any of a set of handoff criteria are satisfied. For example, the associate master participant may assume the role of the master participant if the master participant can no longer perform the functions.

摘要： A novel approach for transferring management functions between participants in a communications arrangement generally involves the use of an associate master participant that assumes responsibilities for functions assigned to the master participant if the master participant can no longer perform the functions. A participant is designated as the master participant and is responsible for performing the functions. Another participant is designated as an associate master participant and assumes the role of master participant if any of a set of handoff criteria, which may vary depending on a particular application's requirements, are satisfied. After the associate master participant assumes the role of master participant, a new associate master participant may be designated. The approach reduces the amount of time required both to determine that the master participant can no longer perform the functions and to assign responsibility for performing the functions to another participant once that determination is made.
摘要翻译：用于在通信安排中的参与者之间传送管理功能的新颖方法通常涉及如果主参与者不能再执行功能，那么使用对主用参与者分配的功能承担责任的副主控参与者。参与者被指定为主参与者，并负责执行功能。另一参与者被指定为副主任参与者，并承担主要参与者的角色，如果根据特定应用程序的要求可能会有所不同的一组切换标准。在副主任参与者担任主参与者的角色之后，可以指定新的副主人参与者。该方法减少了确定主参与者不再执行功能所需的时间量，并且一旦进行了确定，就将负责执行功能的职责分配给另一个参与者。

摘要： An approach for processing data received from a communications channel generally involves equalizing received data in the time domain prior to demodulation by an approach that incorporates mitigation of interference. Oversampling of the received signal provides improved equalization performance and mitigation of interference, such as crosstalk. A receiver oversamples a received signal and splits the signal into a set of observation sequences. The set of observation sequences are processed to provide an estimate of the input to the communications channel, while providing at least partial rejection of any interfering signal. Exact knowledge of the parameters of the interference signal is not required.

摘要： An approach for managing communications channels based on performance involves selecting a particular channel based on channel performance. Based on the selected channel, channel identification data is provided to another participant of the communications system to determine on which channel to respond. For example, the other participant may respond on the selected channel, avoid using the selected channel to respond, or skip the selected channel in a sequence of channels, such as a frequency hopping sequence. The communication sent in response may include a performance measurement of the channel used to provide the channel identification data. According to another aspect of the invention, a particular participant is selected from a group of participants based on the performance of a particular channel. According to yet another aspect, performance data is maintained, such as in a lookup table, and the performance data may be shared between participants of the communications system.

This may be done with a FIR filter, using a cost function of both noise power and impulse response length. Noise power from a variety of sources can be accounted for. Application is particularly directed towards multicarrier systems.
