Abstract

We propose a mitigation technique of high-level multiple access interference(MAI) for multimedia optical Code-Division Multiple-Access(CDMA) systems using the optical power selector. The proposed system can eliminate high-intensity MAI at the receiver for the low-priority users. Moreover, the proposed scheme can reduce by half the required number of code sequences compared to the conventional scheme. As a result, the proposed scheme can obtain higher code spreading gain due to the increase of number of weights at the same code-length. We analyze performances of the proposed scheme and show that both the high-priority users and low-priority users achieve lower bit error rates in comparison to the conventional scheme.
