| titleOfInvention | Probe modulation method, error feedback method, and corresponding device and system |
| abstract | The present invention relates to providing a DSLAM system of multiway xDSL access, and discloses a probe modulation method for eliminating remote end crosstalk of a channel in a DSLAM system, an error feedback method, a crosstalk cancellation coefficient obtaining method, a corresponding network side device, a user side device, a vectorization control entity, and the DSLAM system. The method comprises: calculating, according to a superframe structure parameter and an error feedback parameter of a DSLAM system, the number N of superframes required by an error detected by an uplink feedback on a downlink probe symbol; modulating, according to the calculated N, each probe element of a probe sequence to a downlink probe symbol of M consecutive superframes; and by a detected error fed back by an uplink symbol occupying a maximum of C consecutive superframes on a downlink probe symbol, enabling error feedbacks orderly follow the probe modulation and fully feeding back an error on a probe symbol corresponding to the whole probe sequence. |
