Current optical fibre transmission systems rely on modulation, coding and multiplexing techniques that were originally developed for linear communication channels. However, linear transmission ...

Recently, a sensitivity-enhancement technique for system interrogation using linear controllers and eigenstructure assignment has been extended from linear to nonlinear systems. Nonlinearities have ...

Signals and Systems research broadly covers signals, including images and other forms of information and their acquisition, representation, processing, analysis and interpretation, coding, ...

Non-linear physics is the study of systems where the output is not directly proportional to the input. Unlike linear systems, which follow simple, predictable relationships, non-linear systems exhibit ...
