| 摘 要： | 详细阐述了平行结构和串联结构光纤布喇格光栅编解码器的设计思想,探讨了它们在直接序列扩频光纤码分多址系统中的应用,并推导了各自的编解码原理.通过分析相应系统在功率效率和误码率等方面的性能,得出了最佳的设计参量.结果表明,该编解码器除具有与同一结构类型的光纤延迟线编解码器相似的性能外,还具有相位编解码能力.

| Abstract: | The ladder and parallel encoders/decoders based on fiber Bragg gratings (FBGs) for direct sequence (DS) version of optical code division multiple access (OCDMA) system are investigated.The principles for encoding/decoding are analyzed.The optimal parameters for the encoder/decoder,as well as the system’s power efficiency and bit error rate (BER) are researched.Compared with the encoder/decoder based on fiber delay line (FDL),the ones based on FBGs bring similar performance to DS-OCDMA system.Moreover,they can own capability of phase encoding/decoding. |
