DWMT VDSL을 위한 클럭 복원방식
Clock Recovery Method for DWMT VDSL
초록
DWMT VDSL system needs A/D converter clock, bit clock, symbol clock, frame clock, etc. DMT ADSL system utilizes a correlation method which makes use of cyclic prefix or preamble pattern for clock recovery. But the correlation method is difficult to apply to the DWMT system because modulated symbols are overlapped in the time domain. This paper proposes a novel clock recovery method which can be used for the DWMT system due to its inherent independence of the modulation method. This new method is verified by SPICE simulations.
