Abstract :
Per-survivor iterative timing recovery was proposed to jointly perform timing recovery, equalization, and error-correction decoding. In this paper the robustness of per-survivor iterative timing recovery against thermal asperity (TA) and in ultra-high media noise environment in perpendicular recording channels was investigated.
