摘要： A method and system for performing sequence time domain reflectometry over a communication channel to determine the location of line anomalies in the communication channel is disclosed. In one embodiment, the system generates a sequence signal and transmits the sequence signal over an optical channel. The system receives one or more reflection signals over the optical channel and performs reflection signal processing on the reflection signal. In one embodiment, the optical reflection is transformed to an electrical signal and correlated with the original sequence signal to generate a correlated signal. The time between the start of the reflection signal and a subsequent point of correlation and the rate of propagation reveals a line anomaly location. In one or more embodiments sequence signal time domain reflectometry occurs during data transmission.

摘要： A method and apparatus is disclosed for adaptively determining threshold values in a decision device, such as a decision slicer. In one embodiment, a slicer receives one or more updated threshold values during operation to adaptively accommodate changes in the received signal or the channel that may occur over time. The updated threshold value is based on a MIN value and a MAX value. The MIN values represent a value related to a recently received input that was determined to qualify for a particular slicer output and was less than the particular slicer output value. The MAX values represent a value related to a recently received input that was determined to qualify for a particular slicer output and was greater than the particular slicer output value. In one embodiment, the MAX and MIN value computation is based on scaling factors that dampen the rate of change of the threshold value.

摘要： A method and system for performing sequence time domain reflectometry to determine the location of line anomalies in a communication channel is disclosed. In one embodiment, the system generates a sequence signal and transmits the sequence signal over a channel that is the subject of the sequence time domain reflectometry analysis. The system monitors for and receives one or more reflections, collectively a reflection signal, and presents the reflection signal to a reflection processing module. In one embodiment, the reflection signal is correlated with the original sequence signal to generate a correlated signal. The system may perform signal analysis on the correlated signal to determine a time value between the start of the reflection signal and the subsequent points of correlation. Based on the time value and the rate of propagation of the signals through the channel, the reflection processing module determines a distance to a line anomaly.

摘要： In one embodiment a communication device activation system is provided to restore activation of one or more communication devices that are in a powered-down mode to conserve power usage during a period of inactivity. The activation signal, also referred to as a warm start signal, comprises a sequence signal. A sequence generator generates a desired sequence signal. It is contemplated that one or more sequence signals may be selected for use by the activation system. The sequence signal may be generated or stored and retrieved. To resume communication, a wake-up sequence signal is generated and transmitted to a remote communication device. Upon receipt the received signal is filtered, correlated and analyzed. Analysis may compare one or more aspects of the signal to a threshold signal. If the signal is determined to comprise a wake-up signal, i.e. a request for communication, then a warm-start operation may occur. An acknowledgement signal may optionally be generated to acknowledge receipt of the signal. In one embodiment one or more sequence signals are utilized to monitor channel characteristics and adjust communication device settings accordingly. This may occur as part of the wake-up process.

摘要： A cancellation system is disclosed for processing incoming and outgoing signals in a transform domain to create a cancellation signal for reducing or removing unwanted interference. Data is ordered based on Good-Thomas indexing into a two dimensional array in a buffer. The two dimensional array may have lr rows and lw columns. From the buffer, the columns of data undergo a Winograd small transform. The rows of data undergo a Cooley-Tukey operation to complete the transform operation into the frequency domain. Multipliers scale the transformed data to generate a cancellation signal in the frequency domain. Inverse (Cooley-Tukey) and Winograd transforms perform inverse processing on the cancellation signal to return the cancellation signal or data to the time domain. Re-ordering the data and combination of the cancellation signal or data with incoming or outgoing signals achieve interference cancellation.
