Upstream burst noise measurement and characterization

摘要

Upstream burst noise measurement and characterization. One or more communication devices is implemented to detect and measure burst noise event(s) within channel(s) associated with communication link(s) within communication system(s) or network(s). Detection and measurement of a burst noise event may be made during active communications on one or more other channels, and may be made during active communications on two channels respectively adjacent to the channel on which the burst noise event is being detected and measured. The channel on which the burst noise event is detected and measured may be an unused channel. The detection and measurement of the burst noise event may be made during a quiet time slot within one of the channels. Correlation (e.g., with respect time) may be determined with respect to different respective layers within a communication device (e.g., with respect to MAC and PHY layers).

主权项

1. An apparatus comprising:
at least one input configured to receive communications from a communication channel corresponding to a plurality of channels; a first burst receiver configured to detect and measure a first burst noise event based on energy within a first of the plurality of channels during a first quiet time slot during which the first of the plurality of channels is inactive and unused during active communications on a second and a third of the plurality of channels each being adjacent to the first of the plurality of channels, wherein first measurement of the first burst noise event includes a first duration and a first amplitude; a second burst receiver configured to detect and measure a second burst noise event based on energy within the second of the plurality of channels during a second quiet time slot during which the second of the plurality of channels is inactive and unused during active communications on the first and a fourth of the plurality of channels each being adjacent to the second of the plurality of channels, wherein second measurement of the second burst noise event includes a second duration and a second amplitude; and a scheduler configured to schedule operation of the first burst receiver configured to detect and measure the burst noise event and the second burst receiver configured to detect and measure the second burst noise event.
