Remove receiver and narrowband noise method with a narrow-band noise reduction in high-speed digital subscriber line systems

摘要

PURPOSE: A receiving device is provided to eliminate the narrow band noise in the very high speed digital subscriber line system. CONSTITUTION: The receiving device having the narrow band noise eliminating performance in the very high speed digital subscriber line system comprises: a narrow band noise eliminating piece(30) for extracting the signal highly related with the received signal through the communication channel as a narrow band noise, and for eliminating the extracted signal from the received signals; a lighting unit(40) for compensating the distortion of the signal with its output narrow band noise eliminated; a slicer(50) for slicing the output of the lighting unit(40) by decreasing the difference of the clip level; and a decoder(60) for recovering the output of the slicer(50) as the data transmitted from the information source by decoding the output of the slicer(50).
