Low-complexity turbo equalization using E-BAD detector combine with LDPC codes for high-density magnetic recording

An extend bi-directional arbitrated decision feedback equalizer (E-BAD) was developed from BAD which shown that performance is improved at low error rate. BAD detector can be replaced for the high-complexity detector in turbo equalization for a coded magnetic recording channel which the performance...

Zusammenfassung:An extend bi-directional arbitrated decision feedback equalizer (E-BAD) was developed from BAD which shown that performance is improved at low error rate. BAD detector can be replaced for the high-complexity detector in turbo equalization for a coded magnetic recording channel which the performance is closed. This paper considers a performance evaluation of EBAD detector in turbo equalization with selected LDPC code which the performance is improved while keep low-complexity structure.
