Abstract: An adaptive transversal filter having tap weights Wj which are products of corresponding tap coefficients Cj and tap gains Mj is provided. A filter control loop controls all of the tap coefficients Cj such that an error signal derived from the filter output is minimized. One or more tap control loops controls a tap gain Mk such that the corresponding tap coefficient Ck satisfies a predetermined control condition. For example, |Ck| can be maximized subject to a constraint |Ck| Cmax, where Cmax is a predetermined maximum coefficient value. In this manner, the effect of quantization noise on the coefficients Cj can be reduced. Multiple tap control loops can be employed, one for each tap. Alternatively, a single tap control loop can be used to control multiple taps by time interleaving.

Abstract: The present invention effectively cancels echo, near-end crosstalk and far-end crosstalk. A FEXT canceller is placed at the transmitter rather than at the receiver according to an aspect of the invention. In some embodiment, a FEXT canceller can be placed at the receiver only or the combination of both ends. The FEXT canceller is continuously adapted with information sent back from a remote receiver and with data from a neighbor transmitter that causes the crosstalk at the remote receiver. This allows the FEXT canceller to quickly adapt to a change in crosstalk function or conditions with the surrounding environment, for example, aging, temperature, humidity, physical pressure, etc. In some embodiments, an adaptation control signal is sent back from the receiver to the transmitter by using an overhead bit in the frame format. In some embodiments, part of the FEXT canceller is built-in at the remote receiver.

Abstract: A finite impulse response filter having tap weight rotation is provided, where each tap has a corresponding coefficient selector. Each coefficient selector includes N coefficients, where N is the number of taps. Each coefficient selector provides one of its corresponding coefficients as an input to a multiplier. Each multiplier also receives an input from a triggered track and hold tap. The tap coefficients are selected according to the time delay since the corresponding track and hold tap was most recently triggered. In this manner, the tendency of multiplier gain nonuniformity to degrade filter operation in the presence of tap weight rotation is reduced. In another embodiment, an offset selector is provided, to reduce the tendency of component offsets to degrade filter operation in the presence of tap weight rotation.
