Abstract
A comprehensive study of the noise characteristic in optical balanced receivers in differential phase shift keying (DPSK) systems is performed. The receiver model based on Karhunen-Loève (KL) transform which may include the main transmission impairments in WDM systems is proposed as well as the numerical computation techniques for bit error ratio (BER) assessment. The statistics of the decision current is obtained which shows exact agreement with that of Monte-Carlo simulation, so the analytical result is reliable for accurate estimation of BER. After validated by the time consuming Monte-Carlo error count, the proposed model is adopted in a back-to-back simulation and the 3 dB advantage of DPSK over traditional on-off keying (OOK) is clearly verified.
