| Abstract(in English) | We propose applying turbo coding to the embedded transmission (ET) scheme using pulse position modulation (PPM) in optical code division multiple access (OCDMA). To resolve the problem of the vulnerability of the embedded PPM signaling to multiple access interference (MAI), we obtain the soft information of the received signal, which is used for turbo decoding. We compare the bit error rate (BER) of the proposed scheme with those of the conventional PPM-OCDMA with turbo coding and the ET scheme with BCH coding. Simulation results show that the proposed scheme achieves better BER than the conventional turbo-coded PPM-OCDMA and than the BCH-coded ET scheme. |
