摘要

Malaga大气湍流信道下研究了系统解调模块的相位噪声对无线光副载波相移键控调制系统性能的影响。结合傅里叶级数及MeijerG函数性质，得到了Malaga大气湍流信道模型瞬时信噪比的概率密度函数，在Malaga大气湍流信道下推导了接收信号相位的傅里叶级数以及相位噪声影响无线光副载波 MPSK 调制误符号率的渐进表达式，在不同调制阶数和光强起伏方差下分析了相位噪声对系统误符号率的影响。数值结果表明，当相位噪声较小时，系统误符号率随着光强起伏方差增大而增大，相位噪声较大时，误符号率平层的出现受调制阶数的影响大于受湍流强度的影响，且随着调制阶数的升高，误符号率平层出现时所对应的平均电信噪比越低。

Abstract

The performance of wireless optical system employing subcarrier phase-shift keying modulation was researched

which was influenced by phase noise of system demodulator under on Malaga atmospheric turbulence channel.Combined Fourier series and MeijerG function properties

the probability density function of instantaneous signal to noise ratio in the Malaga turbulence model was got.The Fourier series of receiving signal phase and the closed form expression of symbol error probability were derived

which were in the wireless optical subcarrier shift keying modulation system.Under different modulation order and light intensity fluctuation variance

the influence of phase noise on the system symbol error rate was analyzed.The numeric results present that the system symbol error rate increases with the light intensity fluctuation variance when the phase noise is lower.When the phase noise is larger

the influence of modulation order is greater than of turbulence intensity to the error-rate floor appearing.And with the increasing of modulation order

the corresponding average signal to noise is lower when symbol error-rate floor appears.
