Abstract
The concept of a new coding scheme is proposed, which combines the benefits of a spectral shaping line code and the error correcting capabilities of a convolutional code with Viterbi decoder. A new semi-analytic line code is introduced, which allows partly soft decision outputs from the line decoder. An additional reliability information provided from the line decoder is proposed to enhance the Viterbi decoder performance. Because the coded signal is binary, this transmission scheme is especially well suited for the binary modulation formats commonly used in free space optical communications such as OOK (on-off-keying) or PSK (phase shift keying).
