| 摘 要： | OFDM技术能有效解决塑料光纤（POF）信道中频率选择性衰落及码间干扰等问题。这里在POF通信中引入OFDM技术,建立OOFDM通信模型,分析了高峰均比（PAPR）对POF系统的影响。提出采用脉冲整形技术改变原始数据相位和幅度的分布来抑制PAPR,通过仿真分析了不同基带调制方式对PAPR抑制性能影响,并与几种常见PAPR抑制方法进行比较,最后对模型的整体性能进行仿真。仿真结果表明该技术计算复杂度较小,效率比其他方法高很多,结合QPSK信号调制,降低峰均比效果明显,能有效降低BER值,提高信号质量。

| Abstract: | OFDM can solve problems such as frequency-selective fading and inter-symbol interference(ISI) in POF communication system.Combining OFDM with POF communication technique,an OOFDM communication model is proposed.The impact of high peak power on communication system is analyzed,a method based on pulse-shape and for reducing PAPR of OFDM signals is also suggested.The impact of modulation modes on the performance of pulse-shape method is analyzed and this method is also compared with some existing methods in re... |
