Abstract :
Differential quadrature phase-shift keying (DQPSK) signal has received renewed attention recently for spectral-efficiency transmission systems. Nonlinear phase noise is the major degradation for phase-modulated signals. Correlated with received intensity, nonlinear phase noise can be compensated by the received intensity. The exact error probability of DQPSK signal is derived with and without linear compensation, taking into account the dependence between linear and nonlinear phase noise.
