Robust Matched Filters for Optical Receivers

Minimax Robust Discrete-Time Matched Filters

The problem of designing finite-length discrete-time matched filters is considered for situations in which exact knowledge of the input signal and/or noise characteristics is not available. Such situations arise in many applications due to channel distortion, incoherencies, nonlinear effects, and other modeling uncertainties. In such cases it is often of interest to design a minimax robust matc...

New Gaussian Approximation for Performance Evaluation of Optical Receivers with Arbitrary Optical and Electrical Filters

A new Gaussian approximation (GA) which takes into account the influence of arbitrary optical and electrical filters is proposed for the performance evaluation of optically preamplified receivers. Using the new GA, the receiver sensitivity is evaluated and notable performance differences were observed for several Fabry-Perot optical filters.

Compact Optical Receivers for Coherent Optical Communication

Communication traffic is increasing continuously along with the expansion of video streaming service and the popularization of smartphones and other mobile devices requiring high-speed, large-capacity transmission. Digital coherent optical communication technology using multilevel modulation formats has already been used for long haul systems and is now attracting attention as a means of long-d...
