Distortion comes in two basic classes: Linear distortion, which is not an oxymoron; and nonlinear distortion, which includes all other distortions except noise. Noise is quite another matter and is ...

Digital pre-compensation techniques have emerged as a pivotal tool in modern optical communication systems, addressing the challenges posed by nonlinearity and other system impairments. These methods ...

Achieving unidirectional signal flow—where information travels in only one direction—is vital for next-generation communication systems. Micromechanical devices leveraging parity-time (PT) symmetry ...
