摘要
低成本脉冲光源应用于光码分多址系统,有助于光码分多址系统的实用化进程。对实用化的啁啾脉冲光源应用于光码分多址系统进行了优化改进。研究啁啾脉冲光源本身啁啾的消除即压缩啁啾脉冲对编解码性能的提升作用。针对通常实用的啁啾脉冲光源的谱宽相对较窄而不能充分覆盖编解码频谱的现实,研究利用编解码器频谱的半边带进行编解码以改善解码性能的效果。仿真和实测数据表明,对啁啾脉冲进行消啁啾、压缩脉宽有助于提高编解码性能;利用编解码频谱的半边带进行编解码能够更加充分利用光源频谱,编解码性能进一步得到优化。研究结果表明消啁啾和半边带能够改进啁啾脉冲光源用于光码分多址系统的有效性。
Abstract
The application of low-cost optical pulse source will redound to the practical development of optical code-division multiple-access (OCDMA) system. The application of practical chirped optical pulse source in OCDMA system is improved. The effect of chirp elimination on decoding performance is investigated;The half-side bandwidth of encoding spectrum is utilized for encoding and decoding in order to improve the decoding performance in terms of the fact that the spectrum of common practical chirped pulse source is not wide enough to cover the whole encoding spectrum. The simulation and experimental measured data show that the decoding peformance can be improved via chirp elimination and further optimized by the full utilization of laser source spectrum due to the half-side bandwidth encoding and decoding. The results indicate that the application of chirped optical pulse source in OCDM can be optimized and improved effectively by chirp elimination and half-side bandwidth.
