摘要： A communication device has a transmitting circuit, a receiving circuit, and a controller. The transmitting circuit transmits a first data to a transmission line. The first data is generated by a first scrambler wherein the values of the registers of the first scrambler are characterized by a first combination number. The receiving circuit receives a second data scrambled by a second scrambler from the transmission line. The first and the second scramblers have the same scrambler generator polynomial. The receiving circuit has a descrambler having a plurality of registers for descrambling the second data. The values of the registers of the second scrambler are characterized by a second combination number when the descrambler descrambles the second data. The controller configures the values of the registers of the first scrambler according to the first combination number, the second combination number, and/or a difference between the first and the second combination numbers.
