Nonlinear Echo Cancellation of Data Signals

摘要: This paper describes a new technique for implementing an echo canceller full-duplex data transmission (such as in digital subscriber loops and volceband sets). The can operate spite of time-invariant nonlinearities the channel or implementation itself D/A converters). basic structure linear is not changed, but taps are simply added to account nonlinearity. number which must be depends on degree nonlinearity compensated. Numerical results based computer simulation given show that typical encountered MOS converters compensated by relatively small canceller, substantial improvement cancellation results.
