Iterative Tri-stage Decoding for Turbo Codes in Partial Response Channels
Meng-guang Tsai, Kuen-Suey Hou, Hen‐Wai Tsao · 2005
Combination of turbo codes with partial response (PR) channels was comprehensively studied in magnetic recording systems. In this paper, we investigate a decoding scheme called 'iterative tri-stage decoding' for the turbo code as the outer code and the precoded PR channel as the inner code. This decoding scheme reduces the computational complexities by reducing the number of iterations without degrading the coding gain.
