TMTR Codes for Partial Response Channels

Hui-Feng TSAI, Pi-Hai LIU, Yinyi LIN

Summary :

A TMTR code is specified as (=2,=3,k) constraint. In this work, an approach for constructing (=2,=3,k) codes is presented. Based on this construction, a rate 8/9 code with k=7 is found. This code can achieve better timing recovery performance compared to the proposed previously TMTR code with k=11. An enumerating encoder and decoder exist for constructed (=2,=3,k) codes. A look-up table for the encoder/decoder is not required. Simulation results on an E²PRIV recording channel reveal that the TMTR code provides 2.2 dB gain over an uncoded case.
