Signal quantizations for photon and field channels
Abstract
The paper examines various methods for the quantization of pulsed signals of an optical communication system in the presence of external Gaussian and quantization noise. It is shown that square-law quantization of the photon signal can produce a uniform error rate for each signal level and that uniform quantization can be used for the field signal even when zero level fluctuation is taken into account. In an effort to evaluate the performance of the proposed method applied to practical communication systems, the error rate at each signal level for the case of ten quantization levels is calculated numerically
