In a simulation of compressed sensing (CS), one must test whether the recovered solution (x) over cap is the true solution x, i.e., "exact recovery." Most CS simulations employ one of two criteria: 1) the recovered support is the true support; or 2) the normalized squared error is less than epsilon(2). We analyze these exact recovery criteria independent of any recovery algorithm, but with respect to signal distributions that are often used in CS simulations. That is, given a pair ((x) over cap, x), when does "exact recovery" occur with respect to only one or both of these criteria for a given distribution of x? We show that, in a best case scenario, epsilon(2) sets a maximum allowed missed detection rate in a majority sense. |
