---|---|---|
Suppose that the collection $\{e_{i}\}_{i=1}^{m}$ forms a frame for ℝk, where each entry of the vector ei 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 ℝk can be recovered from its quantized frame coefficients up to an error which decays root-exponentially in the oversampling rate ... |
