Abstract
Non-linear distortion in the form of partial erasure is a primary impediment at high magnetic recording densities. This paper simplifies a decision-feedback tree-search receiver for combating partial erasure. Utilizing an internal flag and a pre-computed threshold lookup table, the proposed receiver requires no multiplications for its metric computation
