| 摘 要： | 正交频分复用是一种多载波调制技术,用于解决各种无线和有线通信系统中因信道色散引起的符号间干扰问题。近年来的研究表明,OFDM在无源光网络方面有广泛地应用前景。文中以OFDM-PON为对象,对其传输性能、动态带宽分配算法进行了研究。提出了基于传统CP算法的改进算法,使OFDM-PON系统的上行带宽分配性能得到改善。经过建模仿真证明,系统上行业务时延和链路利用率都得到了提高。

| Abstract: | Orthogonal frequency division multiplexing (OFDM) is a modulation technique which is now used in most new and emerging broadband wired and wireless communication systems because it is an effective solution to inter symbol interference caused by a dispersive channel.Very recently a number of researchers have shown that OFDM is also a promising technology for passive optical network.The transmission performance of the OFDM-PON system and its dynamic bandwidth allocation algorithm are studied in this paper.The improved algorithm is put forward based on the traditional CP algorithm,achieving upstream bandwidth allocation performance of OFDM-PON system.Modeling and simulating show that both system upstream traffic delay and link utilization are improved. |
