Chaotic signals at different wavelengths can be generated by adjusting the pump power, modulation frequency and tunable filter, and chaos synchronization is achieved.

通过调节泵浦功率、调制频率和可调谐滤波器，可以产生不同波长的混沌信号，并实现混沌的同步。

An improved algorithm for symbol synchronization and symbol decision are proposed. Their performance at different level of SNR and frequency offset are discussed by simulations.

本文提出了一种改进的码元同步算法和改进的码元判决算法，通过仿真分析了它们的抗噪声和抗频偏性能。
