METHOD AND APPARATUS FOR CANCELLING IMPULSE NOISE IN DSL SYSTEMS
摘要
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.
