Abstract:
An economic low-complexity system and method for echo cancellation are disclosed. The system and method are particularly suited for multi-carrier VDSL using the U0 band. The techniques taught herein may be implemented in VDSL and VDSL2 systems and used to receive signals in three bands (e.g., U0, U1 and U2) simultaneously.
