Abstract
This paper analyses and achieves the accurate computational expression of nonlinear phase noise cos(Δφ) in DPSK receivers using optical Mach-Zehnder interferometer (MZI) demodulation and balanced detection of 40Gbit/s system. Then we use it in the BER computation expression considering all the noises to achieve a final accurate computation expression of BER.
