Patent DE-19820909-A1 (DE)
Title: Circuit arrangement of data processing device
Inventor: LIN JINAN
IPC: H04N7/035
Filed: 1998-05-09
Abstract: The received signal is digitized and the  threshold is determined by threshold estimator (LVEST), connected  to decision device (GATG) for deflecting lines containing digital  data. A block level estimator (BLEST) is connected to both LVEST  and GATG. An adaptive equalizer (ADEQ), data rate converter  (RSCL) and bit generator (DPLL) which controls the data rate  converter are also included. The ADEQ corrects channel  interference and DPLL produces correct sampling rate and phase  for the data. The threshold estimator determines mean value of an  input signal and the value is taken as the optimal decision value  for sampling the data bits. The ADEQ corrects different types of  distortion, caused by the transmission channel, without the need  for a training signal.
