  3. Abstract:
  4. In this manuscript, we consider using soft-input decoder for internally bandwidth efficient convolutionally coded fiber-optic Code Division Multiple Access (CDMA) communication systems using Optical Orthogonal Codes (OOC). The convolution codes that are used for demonstrating the capabilities of the soft-input decoder are Super Orthogonal Codes (SOC). These codes are near optimal and have a relatively low complexity. We evaluate the upper bounds on the bit error probability of the internally coded fiber-optic CDMA system using the soft-input and hard-input decoders assuming both On-Off Keying (OOK) and Binary Pulse Position Modulation (BPPM) schemes. It is shown that the soft-input decoder significantly outperforms the hard-input decoder
