Abstract
A system for compensating wire characteristics includes a transmission pre-emphasis module of a transmission transceiver that sends high level pre-emphasis training bits and low level pre-emphasis training bits along a wired connection, a reception pre-emphasis module of a receiver that receives the high level pre-emphasis training bits and low level pre-emphasis training bits along the wired connection, a pre-emphasis analysis module of the receiver that analyzes the high level pre-emphasis training bits and low level pre-emphasis training bits to determine a pre-emphasis level. The system further includes a controller that interfaces with the transmission transceiver and the receiver, the controller communicates the pre-emphasis level to the transmission transceiver.

A system for compensating wire characteristics, the system comprising:
- a transmission pre-emphasis module of a transmission transceiver that sends high amplitude pre-emphasis training bits and low amplitude pre-emphasis training bits along a wired connection;
- and a receiver that receives the high amplitude pre-emphasis training bits and low amplitude pre-emphasis training bits along the wired connection;
- the receiving comprising:
- a pre-emphasis analysis module of the receiver that analyzes the high amplitude pre-emphasis training bits and low amplitude pre-emphasis training bits to determine a pre-emphasis level;
- and
- a controller that interfaces with the transmission transceiver and the receiver, the controller communicating the pre-emphasis level to the transmission transceiver.
A method of compensating for wire characteristics, the method comprising:
- sending pre-emphasis training bits along a wired connection;
- receiving the pre-emphasis training bits along the wired connection;
- analyzing the pre-emphasis training bits to determine a pre-emphasis level;
- and
- communicating the pre-emphasis level to a transmission transceiver;
- wherein the pre-emphasis training bits include a frame sync bit series, a zero bit series and a one bit series;
- wherein the frame sync bit series includes a frame sync bit, the frame sync bit is represented by a half cycle of a sine wave having a first duration;
- wherein the zero bit series includes a zero bit, the zero bit is represented by a half cycle of a sine wave having a second duration;
- wherein the one bit series includes a one bit, the one bit is represented by a half cycle of a sine wave having a third duration;
- wherein at least two of the first duration, second duration and third duration are not equal.
