Abstract
In this paper, we present a single photodiode detection (SPD) technique for spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) systems. The proposed technique eliminates both phase-induced intensity noise (PIIN) and multiple-access interference (MAI) in the optical domain. Analytical results show that for 35 simultaneous users transmitting at data rate of 622 Mbps, the bit-error rate (BER) = 1.4×10−28 for SPD technique is much better compared to 9.3×10−6 and 9.6×10−3 for the modified-ANDa as well as the ANDa detection techniques, respectively. Moreover, we verified the improved performance afforded by the proposed technique using data transmission simulations.
Key words: Optical code-division multiple-access / spectral-amplitude coding / single photodiode detection technique / multiple-access interference / phase-induced intensity noise
The modified-AND as well as the AND are the names of subtraction detection techniques that are proposed in the literature.
