Claim One:
1. A data transmission method, wherein the method is used to exchange data with a sender side, and the method comprises: receiving data sent by the sender side; checking the received data to determine whether erroneous data is detected; determining the erroneous data is detected; discarding the erroneous data and subsequently received non-retransmitted data; sending a data retransmission request to the sender side; counting a bit error rate of retransmitted data from the sender side; determining the bit error rate is not less than a preset bit error rate threshold; and collaborating with the sender side to perform link auto-recovery by transmitting a test code stream based on different compensation parameter combinations, wherein the compensation parameter combinations comprise a receiver-side compensation parameter and a sender-side accentuation parameter, wherein the link auto-recovery success is determined according to existence of a compensation parameter combination in which a bit error rate of transmitting the test code stream is less than the preset bit error rate threshold, and wherein the link auto-recovery failure is determined according to no existence of the compensation parameter combination in which the bit error rate of transmitting the test code stream is less than the preset bit error rate threshold.
