In this paper of Lustig, he speaks about a something which appears unintuitive: sampling at random may exhibit better performance than sampling uniformly. I tried to understand this starting from page 15 of these slides, but I can't really make sense of anything.
Why, if we take random permutation of frequency coefficients, do we get a better reconstruction in terms of signal similarity? Why does this give better reconstruction, and what's the intuition behind the phenomenon?
