| 摘 要： | 采用高斯函数近似方法以及傅里叶变换法分析推导出高速光纤通信技术中所采用的差分相位调制(differential phase-shift keying,DPSK)-平衡接收机系统中的差分非线性相位噪声△ψ的精确表示,把它应用于考虑了所有对接收机误码产生影响的噪声计算公式中,最终得出了DPSK-平衡接收机误码率最终完整的数学表达式,并用VPI软件进行了仿真验证.

| Abstract: | The derivation of the probability density function (PDF) of differential nonlinear phase noise in diffrential phase-shift keying (DPSK)-balanced direct detection receiver of the high speed optical communication system is achieved by using the Gaussian approximation and Fourier transform methods. Finally, the result is used in computing the bit error rate (BER) considering all the noises influenced the transmission performance of the DPSK-balanced receiver system. The results have been verified by simulations through VPI software. |
