Abstract :
A rate 16/17 maximum transition run (MTR) (3;11) code on an EEPRML channel with a postprocessor (turbo-EEPRML) has been developed. The postprocessor compensates for the degradation in performance due to noise correlation. The proposed method has high performance and simple circuitry. Simulation results showed that the rate 16/17 MTR (3;11) code on a turbo-EEPRML channel has a performance gain of 1.0-4.0 dB over a conventional extended partial response maximum likelihood channel with the rate 16/17 run-length-limited code
