A Test for Spectrum Flatness

Author

  • K. Drouiche

Abstract

. We investigate a new tool for measuring whiteness. We first introduce a quantity which has suitable properties for constructing a test for randomness. We provide the exact asymptotic power of our test. Finally, we experimentally assess the power and usefulness of our test.
