多信道光纤通信系统中的间歇动态、强相关和误码率
Intermittent dynamics, strong correlations, and bit-error-rate in multichannel optical fiber communication systems
摘要：
研究了大规模多信道光纤通信系统中延迟喇曼响应对脉冲动力学的影响。考虑到脉冲序列在不同频率通道中的随机性以及脉冲碰撞中拉曼诱导的能量交换，我们发现脉冲参数呈现间歇性的动态行为，脉冲幅度呈现较强的长程相关性。此外，我们发现拉曼诱导的交叉频移是导致比特模式恶化的主要机制，并评估了系统的误码率。
英文摘要：
We investigate the effects of delayed Raman response on pulse dynamics in massive multichannel optical fiber communication systems. Taking into account the stochastic nature of pulse sequences in different frequency channels and the Raman induced energy exchange in pulse collisions we show that the pulse parameters exhibit intermittent dynamic behavior, and that the pulse amplitudes exhibit relatively strong and long-range correlations. Moreover, we find that the Raman-induced cross frequency shift is the main intermittency-related mechanism leading to bit pattern deterioration and evaluate the bit-error-rate of the system.
