Precoded PRML, serial concatenation, and iterative (turbo) decoding for digital magnetic recording Conference Paper uri icon


  • The use of concatenated coding and iterative decoding to improve the error performance of a partial response equalized magnetic recording channel is addressed. It is shown that outstanding performance is achievable without the use of turbo codes. In particular, it is demonstrated that a high rate serially concatenated code used in conjunction with a conventional NRZI precoder and iterative decoding can provide essentially identical performance.
