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.

主权项

1. A method for wireless communication, comprising:
combining per-tone frequency information from a first sensor and a second sensor; detecting impulse noise based at least in part on the combined per-tone frequency information; and selectively training an impulse noise canceller while in a data transmission mode based at least in part on an amount of the detected impulse noise.
