Abstract
A detection method includes: obtaining a decision feedback equalizer coefficient, where the decision feedback equalizer coefficient includes a tap coefficient; obtaining a decision signal sequence of a decision feedback equalizer; determining a first location of a decision signal of a start of burst error in the decision signal sequence when the tap coefficient is less than or equal to a first preset threshold; and determining a second location of a decision signal of an end of burst error in the decision signal sequence based on the first location.
Claims20
A location detection method comprising:
- obtaining a decision feedback equalizer coefficient comprising a tap coefficient;
- obtaining a decision signal sequence of a decision feedback equalizer;
- determining a first location of a first decision signal of a start-of-burst error in the decision signal sequence when the tap coefficient is less than or equal to a preset threshold;
- and
- determining a second location of a second decision signal of an end-of-burst error in the decision signal sequence based on the first location.
A location detection apparatus comprising:
- a non-transitory memory configured to store instructions;
- and
- one or more processors coupled to the non-transitory memory and configured to execute the instructions to cause the location detection apparatus to:
- obtain a decision feedback equalizer coefficient comprising a tap coefficient;
- obtain a decision signal sequence of a decision feedback equalizer;
- determine a first location of a first decision signal of a start-of-burst error in the decision signal sequence when the tap coefficient is less than or equal to a preset threshold;
- and
- determine a second location of a second decision signal of an end-of-burst error in the decision signal sequence based on the first location.
A non-transitory computer-readable storage medium storing a program, that when executed by one or more processors, causes a location detection apparatus to:
- obtain a decision feedback equalizer coefficient comprising a tap coefficient;
- obtain a decision signal sequence of a decision feedback equalizer;
- determine a first location of a first decision signal of a start-of-burst error in the decision signal sequence when the tap coefficient is less than or equal to a preset threshold;
- and
- determine a second location of a second decision signal of an end-of-burst error in the decision signal sequence based on the first location.
