Query: Coherence Statistics of Structured Random Ensembles and Support
  Detection Bounds for OMP   A structured random matrix ensemble that maintains constant modulus entries
and unit-norm columns, often called a random phase-rotated (RPR) matrix, is
considered in this paper. We analyze the coherence statistics of RPR
measurement matrices and apply them to acquire probabilistic performance
guarantees of orthogonal matching pursuit (OMP) for support detection (SD). It
is revealed via numerical simulations that the SD performance guarantee
provides a tight characterization, especially when the signal is sparse.
