Abstract
Provided are a sampling clock phase mismatch error estimation method and apparatus, and a storage medium. This sampling clock phase mismatch error estimation method includes: a proportional relation between an estimation operator of a modular square subtraction method corresponding to each frequency interval of multiple frequency intervals and a sampling clock phase mismatch error of a time-interleaved analog to digital converter (TIADC) is acquired; a slope and an offset value of a fitting proportion line segment are counted; and a slope of a proportion line segment corresponding to a real-time estimation frequency is converted, and an offset value corresponding to the real-time estimation frequency is estimated through an interpolation according to a counted slope and a counted offset value, and the actual value of the sampling clock phase mismatch error is estimated according to a converted slope and an offset value estimated through the interpolation.
