| Abstract(in English) | Degradation of bit error rate by multi user interferences (MUI) was considered asa big problem for direct modulation optical CDMA systems because they used unipolar codes as signature codes. Single OHL system and Double OHL system are proposed to reduce these MUIs. But, it is not clear the property of BER where APD noise is taken into account. Also it is not clear how the second OHL reduces BER. Quantum noises are not considered in the OHL yet. These problems are considered here. |
