UPDATING ADAPTIVE EQUALIZER COEFFICIENTS USING KNOWN OR PREDICTABLE BIT PATTERNS DISTRIBUTED AMONG UNKNOWN DATA

摘要

The built-in pattern- based adaptive equalizer coefficient update mechanism (60) is a known signal pattern ( 100 ) has a copy of the adaptive equalizer 40, so the repetitive pattern of the modified signal with the known error or deviation signal obtained by processing the version to be distributed among the information signal included in the output electrical signal from the equalizer of the communication and updates the weighting coefficient . Only having a transmission , a training sequence , because communication is not required, the coefficient updating mechanism does not affect the operation of the channel bandwidth utilization .
