| 摘 要： | 为了解决多模光纤(MMF)通信系统中的自适应调制光正交频分复用(AMO-OFDM)技术存在的算法复杂度、自适应调制方案的具体硬件实现难度大等问题,本文提出了一种自适应功率分配光正交频分复用(APAO-OFDM)技术,并给出了一种高效的自适应功率分配算法.仿真结果表明,等信噪比(SNR)功率分配方式的APAO-OFDM技术能够获得与AMO-OFDM技术相近的最大传输速率性能,当最大传输速率低于14 Gbit/s时两者需要的发射光功率几乎相等.

| Abstract: | A novel technique named adaptive power allocation optical orthogonal frequency division multiplexing(APAOOFDM) is proposed in this paper.The efficient adaptive power allocation algorithm is also developed.In comparison with the adaptively modulated optical orthogonal frequency division multiplexing(AMO-OFDM) technique,the simulation results show that the two techniques based on equal SNR power allocation can achieve similar maximum transmission performance,but the cost of APAO-OFDM may be low.In addition,th... |
