摘要： Differential feedback within multiple user, multiple access, and/or MIMO wireless communications. After full feedback signal(s) have been received by a communication device (e.g., one that is to be performing beamforming for use in subsequent signal transmission), differential feedback signal(s) are received. Those differential feedback signal(s) are employed to update the full feedback signal(s) thereby generating updated/modified full feedback signals. Over time, such updated/modified full feedback signals may subsequently be further updated based upon later received inferential feedback signal(s). Such differential feedback signaling takes advantage of time and/or frequency correlation in a communication channel to provide for reduced feedback overhead by feeding back a difference or delta (Δ) relative to a previous value. For example, instead of providing full feedback signals in each respective/successive communication, feedback overhead is reduced by providing a difference or delta (Δ).

摘要： Group identification and definition within multiple user, multiple access, and/or MIMO wireless communications. A group identification definition field may be transmitted to a number of receiving devices for use in interpreting current or subsequently received packets that include a group identification field (group ID). The group ID can serve a number of functions such as indicating those receiving devices for which the packet is intended, the identification of fields within the packet corresponding to the various devices, certain parameters (e.g., code type, code rate, modulation type, etc.) associated with such fields within the packet, etc. The group identification definition field may be updated or modified to allow for modification of the manner in which subsequent packets, including respective group IDs, are processed. One of a variety of events may direct the group identification definition field may be updated or modified.

摘要： Synchronized UWB piconets for SOP (Simultaneously Operating Piconet) performance. A common backbone (either wired or wireless) is employed that provides a common CLK (clock signal) to all of the various PNCs (piconet coordinators) of various piconets that may operate within a sufficiently close region such that interference could undesirably occur. By providing a very reliable CLK signal from a common backbone to all of the PNCs of the various piconets operating within a substantially close proximity to one another, very precise synchronization may be ensured for all of the communications performed therein. The various piconets may then even operate using TDMA (Time Division Multiple Access)—whose performance would be substantially compromised without effective synchronization. In addition, combined TFC (time frequency code) and TDMA may also be employed to support the communications therein thereby providing even another degree of orthogonality that provided by TDMA alone.

摘要： Multi-band single-carrier modulation. A novel approach is presented by which interference compensation may be performed for signals received by a piconet operable device. The piconet operable device may be implemented within a region that includes two or more SOPs (Simultaneously Operating Piconets). Estimation of the level and location of interference is performed and the input to a decoder (within the piconet operable device) is selectively weighted to ensure that the effect of any existent interference within the signal received by the piconet operable device is minimized. Different interference levels are dealt with differently. For one example, portions of the received signal having undergone a large amount of interference may be simply treated as erasures with respect to the input the decoder. For another example, portions of the received signal having undergone some smaller degree of interference, but some interference nonetheless, may be de-weighted before being provided to the decoder.

摘要： A filter settings generation operation includes sampling a communication channel to produce a sampled signal. The sampled signal is spectrally characterized across a frequency band of interest to produce a spectral characterization of the sampled signal. This spectral characterization may not include a signal of interest. The spectral characterization is then modified to produce a modified spectral characterization. Filter settings are then generated based upon the modified spectral characterization. Finally, the communication channel is filtered using the filter settings when the signal of interest is present on the communication channel. In modifying the spectral characterization, pluralities of spectral characteristics of the spectral characterization are independently modified to produce the modified spectral characterization. Modifications to the spectral characterization may be performed in the frequency domain and/or the time domain. One particular spectral modification that is performed is raising of the noise floor of the spectral characterization to meet a budgeted signal-to-noise ratio. Other spectral modifications include modifying spectral components corresponding to an expected interfering signal. In modifying these spectral characterizations, spectral components corresponding to a plurality of expected interfering signals may be modified.
