摘要

The triple-branch signal detection (TBSD) scheme can eliminate multiple-user interference (MUI) without fixed in-phase cross-correlation (IPCC) stipulation in the spectral-amplitude-coding optical code division multiple access (SAC-OCDMA) systems. In this paper, we modify the traditional TBSD scheme and theoretically analyze the principle of the MUI elimination. Then, the bit-error-rate (BER) performance of the modified TBSD scheme is investigated under multiple transmission rates. The results show that the modified TBSD employing the codes with unfixed IPCC can achieve simultaneous optical code recognition and MUI elimination in the SAC-OCDMA.
