摘要

迭代信号限幅（ISC）和符号分解串行传输（SDST）技术将光正交频分复用（O-OFDM）符号分解为固定数量的多个小幅度符号，但当 O-OFDM 符号方差较小时，分解符号中有大量不载荷信息的全零符号，导致误码率变差、光功率损耗和信息速率降低。针对这一问题，提出了自适应 O-OFDM 符号分解串行传输（ASDST）系统，根据O-OFDM符号的幅度大小自适应决定符号分解，直到O-OFDM符号完全分解或达到最大符号分解次数，从而消除了全零符号，减少了平均符号分解次数。理论分析和蒙特卡罗仿真验证了ASDST系统的性能。

Abstract

Iterative signal clipping (ISC) and symbol decomposing with serial transmission (SDST) techniques decompose optical orthogonal frequency division multiplexing (O-OFDM) symbol into the fixed number of multiple small-amplitude symbols.However

at low O-OFDM symbol variances

the decomposition symbols contain a large amount of all-zero symbols without load information

which results in bit error rate degradation

optical power penalty and information rate reduction.Aim at this problem

an adaptive O-OFDM symbol decomposing with serial transmission (ASDST) system was proposed

the symbol decomposition was adaptively determined according to the O-OFDM symbol amplitude.Symbol decomposition was terminated until O-OFDM symbol was completely decomposed or the maximum symbol decomposition times were attained

thereby eliminated all-zero symbols and reduced the average symbol decomposition times.The performance of ASDST system was verified by theoretical analysis and Monte Carlo simulation.
