This paper describes a novel approach to quantization in oversampled filter banks. The new technique is based on moving horizon optimization, does not rely on an additive white noise quantization model and allows stability to be explicitly enforced in the associated nonlinear feedback loop. Moreover, the quantization structure proposed here includes SigmaDelta and linear predictive subband quantizers...
There are two major issues which underly the design of an analog to digital converter; namely "when to sample?" and "how to represent the amplitude of each sample?". In the majority of past work, these two aspects have typically been treated separately. Recently (Derpich et al., 2005) we have introduced a novel algorithm called MSIC which uses moving horizon optimization ideas...
