DYNAMIC OPTIMIZATION OF OVERLAP-AND-ADD LENGTH

摘要

A method of adjusting overlap-and-add length for zero-padded suffixes. The method includes, based on a channel impulse response, estimating an effective channel length. When the effective channel length is less than a default overlap-and-add length and greater than a minimum length, the method includes setting the overlap-and-add length to the effective channel length. When the effective channel length is less than the minimum length, the method includes setting the overlap-and-add length to the minimum length. When the effective channel length is greater than the default overlap-and-add length, the method includes setting the overlap-and-add length to the default overlap-and-add length.
