摘要： A novel mechanism for sharing filter taps across a plurality of interference cancellers. Each interference canceller may be directed to impairment, such as Ethernet impairments, including Ethernet 1000Base-T impairments. Various interference impairments include echo cancellation, NEXT cancellation and/or other interference detection or cancellation, etc. The hardware requirements of the interference impairment cancellers are reduced by sharing filter taps among the cancellers. In a first embodiment, the taps from a unified filter tap bank are shared across all the interference impairment cancellers for all four channels and over all ports. In a second embodiment, a portion of the taps of each filter are shared wherein each canceller comprises a fixed filter tap portion and a shared filter tap portion. A tap allocation algorithm assigns taps to those cancellers that need them the most. A canceller configuration is selected that yields maximal interference mitigation and the taps are allocated accordingly.

摘要： A communication terminal includes a Radio Frequency (RF) unit and a baseband processor. The RF unit is operative to receive signals from a Base Station (BS) of a wireless communication network using a communication protocol that defines time frames divided in a time domain into zones. Each zone corresponds to a respective communication mode between the BS and the terminal and occupies respective time intervals within the frames.The baseband processor is coupled to receive from the BS via the RF unit synchronization information indicating whether the time intervals allocated to at least a given zone by the BS and by at least one other BS of the wireless communication network are synchronized with one another, and to process the signals received from the BS so as to cancel, responsively to the synchronization information, interference caused to the signals by the at least one other BS.

摘要： A novel and useful mechanism for the detection and estimation of far-end cross talk (FEXT) caused by transmissions over adjacent wire pairs or cables. The detection and estimation technique of the invention can be used to identify FET impairments in Ethernet and DSL systems. The detection and estimation scheme is performed utilizing an adaptive FEXT canceller filter for detection purposes during normal operation of the system. FEXT filter tap coefficients are determined one at a time using a mechanism shared amongst all taps. Once adapted, the filter coefficients can be used to estimate FEXT strength and to determine spectral measurements of the FEXT impairment noise.

摘要： A novel and useful mechanism for shutting down very small canceller taps that have little influence on the output of the canceller. Disabling or completely disabling these taps results in a significant reduction in power consumption of the circuit incorporating the canceller. Shutting down very low valued canceller taps also results in reduced least mean square (LMS) noise caused by the jittering of the smaller taps of the canceller. Several methods are provided that determine the number and location of the taps to be shutdown. The mechanism of the invention is operative to shut down canceller taps that are lower than a predetermined threshold. Methods include comparing each individual tap to a threshold, comparing an average of each tap to a threshold, comparing groups of taps to a threshold and comparing an average of groups of taps to a threshold. Taps or groups of taps are smaller than the threshold are shutdown thus reducing the power consumption of the canceller.
摘要翻译：一种新颖有用的机制，用于关闭对消除器的输出影响很小的非常小的消除器水龙头。禁用或完全禁用这些抽头导致包含消除器的电路的功耗显着降低。关闭非常低的值的消除器抽头也导致由消除器的较小抽头的抖动引起的最小均方（LMS）噪声的降低。提供了确定要关闭的水龙头的数量和位置的几种方法。本发明的机构可操作以关闭低于预定阈值的消除器抽头。方法包括将每个单独抽头与阈值进行比较，将每个抽头的平均值与阈值进行比较，将抽头组与阈值进行比较，并将抽头组的平均值与阈值进行比较。抽头或抽头组小于阈值，因此减小了消除器的功耗。
