摘要

采用符号预编码技术降低峰均功率比，对城域网10gbit /s直测系统中单边带OFDM信号的性能进行了实验评价。符号预编码技术在不增加OFDM信号多余带宽的情况下实现了3 dB的PAPR降低。实验表明，在150公里标准单模光纤传输中，误码率提高了一个数量级以上。

Experimental demonstration of PAPR reduction in 10 Gbit/s SSB-OFDM direct-detection systems through symbol precoding

The performance improvement of single-sideband orthogonal frequency division multiplexing (OFDM) signals in 10 Gbit/s direct-detection systems for metropolitan telecommunication networks, by reducing the peak-to-average power ratio (PAPR) with a symbol precoding technique is assessed experimentally. The symbol precoding technique achieves a 3 dB PAPR reduction without adding excess bandwidth to the OFDM signal. A bit error ratio improvement of more than order of magnitude is experimentally shown along 150 km standard single mode fiber transmission.
