摘要

我们讨论了高速率涡轮码对磁记录的适用性，特别是引用了与编码增益相反的交织增益的吸引力。然后，我们在用户密度为S/sub /=2.0的情况下，研究了速率4/ 5,8 /9和16/17 turbo码在pra均衡磁记录信道上的性能。仿真结果表明，在错误率为10/sup -5/的情况下，速率为4/5和8/9的码相对于未编码的情况可获得7.1 dB的增益，而速率为16/17的码可获得6.5 dB的增益。

Performance of high rate turbo codes on a PR4-equalized magnetic recording channel

We discuss the applicability of high rate turbo codes for magnetic recording, citing in particular the attractiveness of interleaver gain as opposed to coding gain. We then examine the performance of rate 4/5, 8/9, and 16/17 turbo codes on a PRA-equalized magnetic recording channel at a user density of S/sub u/=2.0. Simulation results show that a gain of 7.1 dB relative to the uncoded situation is attainable at an error rate of 10/sup -5/ for the rate 4/5 and 8/9 codes, whereas the rate 16/17 code achieves a gain of 6.5 dB.
