Abstract(in English) | In this paper, we propose the optical CDMA systems with M-ary pulse-amplitude modulation(PAM) using the chip-level receiver with M-level threshold detection. The proposed system can obtain the synergistic effect, which the chip-level receiver reduces the large effect of MAI in the PAM-CDMA system with the correlator and PAM has the larger number of transmitted bits per frame than the OOK-CDMA system. As a result, the proposed system can increase the code length and the number of weights, and achieve higher tolerance to MAIs under the condition where the chip duration, the bit rate and the number of subscribers are kept constant. We show that the proposed M-ary PAM-CDMA system with the chip-level receiver achieves better bit error probability (BEP) than the OOK-CDMA system with the chip-level receiver. |
