Before revision:  We evaluate the coset correlation matrix estimation and analyze the statistical performance of the compressively reconstructed periodogram , which includes a bias and variance analysis. We then consider the case when the size of the bin is decreased such that the received spectra at two frequencies or angles, with a spacing between them larger than the size of the bin, can still be correlated.
