摘      要：The analytical expression of bit error probability in a balanced differential phase-shift keying(DPSK) optical receiver considering nonlinear phase noise and EDFA ASE noise is given,which is very useful to estimate the performance of DPSK balanced and unbalanced receiver in optical communication *** analysis,if only nonlinear phase noise is considered,both the balance and unbalanced receivers have the same *** if adding the ASE noise of EDFA,the balanced receiver is better.
