Abstract

A theoretical study of the transmission performance of the optical orthogonal frequency division multiplexing (OFDM) system was conducted as a function of number of subcarriers. It revealed that small number of subcarriers could improve the transmission performance because the optimum repeater output power of the system was increased. The reason of the improvement could be attributed to the nonlinear impairment reduction through the peak to average power ratio (PAPR) reduction.

摘要

针对光正交频分复用（OFDM）系统的传输性能，开展了一项作为子载波数量函数的理论研究。研究表明，较少数量的子载波可以改善传输性能，因为系统的最佳中继器输出功率增加了。性能改善的原因可归因于通过降低峰均功率比（PAPR）减少了非线性损伤。
