High-performance quantization for spectral super-resolution
High-performance quantization for spectral super-resolution
We show that the method of distributed noise-shaping beta-quantization offers superior performance for the problem of spectral super-resolution with quantization whenever there is redundancy in the number of measurements. More precisely, if the (integer) oversampling ratio λ is such that $\left\lfloor {M/\lambda } \right\rfloor - 1 \geq 4/\Delta $, where …
