Document Type and Number:
WIPO Patent Application WO/2014/063116
Kind Code:
A3
Abstract:
The present invention generally relates to an impulse noise canceller for DSL systems. According to certain aspects, embodiments of the invention provide a dual sensor receiver to deal with the impulse noise effectively. The second sensor can be incorporated by either a common mode or unused differential port. Alternatively a power line sensor can also act as a sensor. According to certain additional aspects, embodiments of the invention provide various alternative implementations of an impulse noise canceller within a DSL receiver, According to still further aspects, embodiments of the invention provide methods for selectively training an impulse noise canceller in the various implementations,
