An RIP-based approach to $ΣΔ$ quantization for compressed sensing

In this paper, we provide a new approach to estimating the error of reconstruction from $ΣΔ$ quantized compressed sensing measurements. Our method is based on the restricted isometry property (RIP) of a certain projection of the measurement matrix. Our result yields simple proofs and a slight generalization of the best-known reconstruction error bounds for Gaussian and subgaussian measurement matrices.
