CODE-BASED ECHO CANCELLATION
First Claim
1. An apparatus for canceling a signal comprising:
- an identification code (ID code) generator configured to generate an ID code;
an ID code injector configured to inject the ID code into at least one of the signal and a processed signal to produce a convolved signal, the processed signal resulted from a processing of the signal;
an ID code detector configured to detect at least one of the convolved signal, a transformed signal, and a transformation of the convolved signal, the transformed signal resulted from the transformation of the convolved signal; and
an arithmetic function configured to remove at least one of the convolved signal and the transformed signal.

Abstract
An apparatus for canceling a signal is disclosed. The apparatus may include an identification code (ID code) generator configured to generate an ID code. The apparatus may also include an ID code injector configured to inject the ID code into at least one of the signal and a processed signal to produce a convolved signal. The processed signal is resulted from a processing of the signal. The apparatus may further include an ID code detector configured to detect at least one of the convolved signal, a transformed signal, and a transformation of the convolved signal. The transformed signal is resulted from the transformation of the convolved signal. The apparatus may further include an arithmetic function configured to remove at least one of the convolved signal and the transformed signal.
