| Abstract(in English) | In the Optical Code-Division Multiple Access (OCDMA), which is expected as a communication system of next-generation, decoded signals include low-voltage noises issuing from the mutual correlation between the main signal and the multiplexed other channel signals. In this report, a noise reduction method from the electrical signals which were converted from decoded optical signals are presented. The noise reduction system consists of a peak-voltage-control circuit and a threshold amplifier. The circuits have been designed and fabricated, and noise reduction experiments using real OCDM signals are carried out. The experimental results showed the bit-error rate improvement of about 10^<-3>, which showed the noise reduction method is effective for OCDM. |
