A universal negative group delay filter for the prediction of band-limited signals
A filter for universal real-time prediction of band-limited signals is presented. The filter consists of multiple time-delayed feedback terms in order to accomplish anticipatory coupling, which again leads to a negative group delay for frequencies in the baseband. The universality of the filter arises from its property that it does not rely on a specific model of the signal. Specifically, as lo...

Background According to reports of the German Public Health Department, up to 80% of the children suffer on postural weakness. Most of them develop during the adolescent growth severe spine diseases like scoliosis. In case of slight postural deformity, patients are able to influence actively the posture of the spine by physiotherapy and training of stance and behaviour [1]. In advanced cases th...

متن کاملUniversal Zero-Delay Joint Source-Channel Coding
We consider zero-delay joint source-channel coding of individual source sequences for a general known channel. Given an arbitrary finite set of schemes with finite-memory (not necessarily time-invariant) decoders, a scheme is devised that does essentially as well as the best in the set on all individual source sequences. Using this scheme, we construct a universal zero-delay joint source-channe...
متن کاملTime-delay Systems with Band-limited Feedback
Fast nonlinear devices with time-delayed feedback, developed for applications such as communications and ranging, typically include components that are ACcoupled, i.e. components that block zero frequencies. As an example of such a system, we describe a new opto-electronic device with band-limited feedback that uses a Mach-Zehnder interferometer as passive nonlinearity and a semiconductor laser...
