摘要

噪声和非线性特性是影响子载波光传输无线接入系统的重要因素。由于E/O产生的三阶互调失真(IM3)可以忽略，为了提高载波噪声比(CNR)，提出了频率排列信号提取(SEFA)方法。仿真结果表明，SEFA大大提高了传输性能。该技术将使更便宜的E/O设备实现到面向光纤的无线接入系统中成为可能。

Signal extraction with frequency arrangement (SEFA) schemes in fiber-oriented wireless access systems

Noise and non-linearity characteristics are very important factors for wireless access systems using subcarrier optical transmission. The signal extraction with frequency arrangement (SEFA) is proposed for improving carrier-to-noise ratio (CNR) because the 3rd-order intermodulation distortion (IM3) produced by E/O can be ignored. Simulation results show that SEFA greatly improves the transmission performance. This technology will make possible cheaper E/O device implementation into a fiber-oriented wireless access systems.
