摘要： A system for canceling impulse noise comprises an adaptive impulse canceler and a combiner. The adaptive impulse canceler is configured to receive a common mode component of a received signal and to detect a noise impulse in the common mode component. The impulse canceler is further configured to provide, based on the noise impulse in the common mode component, an impulse noise estimation for a differential mode component of the received signal. The combiner is configured to receive the differential mode component and the impulse noise estimation and to subtract the impulse noise estimation from the differential mode component.

摘要： A method of training and operating a dual-duplex, four-wire communications system to provide for time alignment in the receivers of data that is time aligned in the transmitters, even in the presence of a differential transmission delay in the wire pairs. In a training mode, a known sequence of training data is concurrently sent across each wire pair such that equalizers in the receivers are forced to train together. After the equalizers have been trained to eliminate the differential delay, the system is switched to a data mode.

摘要： A cascaded signal processing arrangement processes digitally encoded voice samples transported over a time division multiplex (TDM) communication path for application to a processor-controlled digital communication device, in particular an integrated access device. Processed voice samples are packetized in accordance with an encapsulating protocol and transmitted as a packetized voice output stream to a destination receiver device. The arrangement includes an echo canceller coupled to the TDM communication path and performing echo cancellation processing on the digitally encoded voice samples. The echo cancellation-processed voice sample signals are compressed by a data compression operator and applied to a packet encapsulating host processor via the TDM communication path. This obviates the necessity of the host processor having to use data bus cycles to download processed digitized voice samples.

摘要： A system for adaptively updating precoder taps comprises a first signal path, a second signal path, a delay mechanism, and logic. The first signal path is configured to receive encoded signals. The first signal path has a decoder that is configured to decode the encoded signals thereby recovering data originally transmitted from a remote transmitter. The delay mechanism is configured to receive and delay the encoded signals. The second signal path is connected in parallel with the first signal path and is configured to receive the encoded signals delayed by the delay mechanism. The second signal path has an adaptive filter configured to filter the encoded signals received by the second signal path based on a set of coefficients of the adaptive filter. The adaptive filter is configured to adaptively update the coefficients based on the data recovered by the first signal path. The logic is configured to adaptively generate new precoder taps based on the coefficients and to transmit the new precoder taps to a precoder.

摘要： A system and method for transmitting data over a twisted pair with or without load coils using a transmitter and receiver is disclosed. The system detects load coils by generating and transmitting a test signal having signal power concentrated in two different frequency bands across the twisted pair and comparing the signal power of the received signal to determine whether the twisted pair is loaded or unloaded. If load coils are detected, an adjustment circuit is used to configure the receiver for reception of data over a twisted pair having load coils. Otherwise, the adjustment circuit configures the receiver for reception of data over a twisted pair without load coils.
