FFT filter-bank-based wideband detection: Coherent vs. non-coherent integration
Sichun Wang, Robert Inkol, Sreeraman Rajan, François Patenaude · 2009
Mathematical formulas are derived for computing the relative performance gains obtainable with non-coherent and coherent integration in the detection of narrowband signals using an FFT filter bank. Numerical results are provided for typical implementation parameters. These results are useful for making appropriate tradeoffs in the design of solutions for practical signal detection problems.
