ABSTRACT
Signals and noise are important parameters to determine the quality of any engineering system, especially in the telecommunications field. The modulated signals under different modulation formats will be treated in subsequent chapters. This chapter presents an overview of the noise process and mechanism in terms of equivalent noise power and contribution to the optoelectronic process at the optical receiver. Further, the integration of the noise and the statistical process for determination of the receiver sensitivity under transmission of different modulation formats are described together with modeling techniques in the MATLAB® and Simulink® platform. Statistical analyses are also given for the evaluation of the transmission performance, especially when there are no uniform probability distributions.
