| Summary |
We propose a method to realize the soft-decision decoding for the hard-detected signals. In this paper, a novel concept is introduced as "error-detected reliability". The method is very useful for
fiber optical communication systems as hard detection is the only
detection method for the systems. We demonstrate our proposed
method using the turbo code in which the soft information is required
for the decoding. As a result, the simulation shows slight difference
in the range of moderate to high signal-to-noise ratio between the
proposed decoding scheme and the conventional turbo decoding. Moreover,
the bit error rate of 10^-11 can be achieved by serial
concatenation of Reed-Solomon and turbo code for Q-factor lower than
8.0 dB with the bandwidth expansion ratio of 33.3%.
