標題: | Exact Evaluation of the Capacity for Intensity-Modulated Direct-Detection Channels With Optical Amplifier Noises | 作者: | Ho, Keang-Po | 關鍵字: | Channel capacity;direct-detection;on–off keying | 公開日期: | 四月-2005 | 出版社: | Taipei:National Taiwan University Dept Comp Sci Informat Engn | 卷: | VOL. 17 | 期: | NO. 4 | 起(迄)頁: | - | 來源出版物: | IEEE PHOTONICS TECHNOLOGY LETTERS | 摘要: | Based on a rigorous model without approximation, the channel capacity is evaluated numerically for intensity-modulated direct-detection systems dominated by optical amplifier noises. With a discrete probability at zero intensity, the optimal input distribution is both discrete and continuously distributed. For small signal-to-noise ratio less than about 5 dB, the optimal signal is binary on–off keying. |
