Sigma-Delta quantization of sub-Gaussian frame expansions and its application to compressed sensing

Suppose that the collection forms a frame for k , where each entry of the vector e i is a sub-Gaussian random variable. We consider expansions in such a frame, which are then quantized using a Sigma-Delta scheme. We show that an arbitrary signal in k can be recovered from its quantized frame coeffic...
