Abstract

In this paper we present a rigorous treatment for evaluating the performance of a differential phase shift keying system using optical preamplification and optical demodulation. This treatment is based on the characteristic function an allow us to analyze the influence of the post-detection filtering on the non-Gaussian noise sources, resulting from amplified spontaneous emission noise beats. Both lumped and distributed Erbium-Doped Fiber Amplifiers with single and dual pumping schemes have been considered. Our results, when compared with the Gaussian approximation, indicate that this approximation overestimates the bit error rate and becomes inadequate as the bit rate increases.
