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; 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 an bit error rate of transmitting the test code stream meets the first preset condition, 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 meets the first preset condition.
