## Trace interpolation by prediction-error filter simulation (PEFS)

#### Jun Ji

By simulating a prediction-error filter using the dips picked from
a dip spectrum, I devise an interpolation scheme.
The procedure has three stages: (1) First of all, the dips of linear events
in a given data set are estimated from the dip spectrum obtained
from the slant stack. (2) Next, the prediction error filters in the $(f,x)$
domain are simulated by putting zeros along the dips picked
in the $(f,k)$ spectrum.
(3) Finally, missing traces are found by minimizing the filtered output
in the least square sense.
The advantage of this approach lies in its ability to handle multi-dips
in both regularly and irregularly sampled traces.
