Method and apparatus for echo cancellation in an asymmetric communication system

   
   

A method and system for canceling echo signals originating from a transmitter at a predetermined data rate. The echo signals are received by a receiver at a different data rate. The echo system is configured to manipulate data rates of transmitted signals, and reconstruct echo signals for consideration by the receiver. In view of the band-limited nature of these echo signals, the invention intelligently reduces the computational complexity of reconstructing and canceling echo signals.

Um método e um sistema para cancelar o eco sinalizam originar de um transmissor em uma taxa de dados predeterminada. Os sinais do eco são recebidos por um receptor em uma taxa de dados diferente. O sistema do eco é configurarado para manipular taxas de dados de sinais transmitidos, e reconstruct sinais do eco para a consideração pelo receptor. Na vista da natureza band-limited destes sinais do eco, a invenção reduz inteligente a complexidade computacional de reconstructing e de cancelar sinais do eco.
