摘要:
分析了基于PGC解调方案的DCM技术和反正切函数法(arctangent)的原理,并讨论了反正切函数法中载波信号幅度C的选择标准.与DCM技术相比,反正切函数法具有原理简单,受光功率波动的影响小,对光源的要求低等优点.仿真实验结果表明反正切函数法具有良好的解调效果和实际可行性.
Abstract:
The principles of the DCM approach and arctangent approach based on PGC demodulation were described. The criteria for selection of the amplitude of carrier signals were discussed in detail. In comparison with DCM approach, the arctangent approach is simple in principle, with little influence of the fluctuation of laser power and the low requirement on the laser. The results of simulation demonstrated that the arctangent approach has outstanding demodulation effect. Simulation experiment proves the feasibility of the arctangent approach.
