Random matrix approach in search for weak signals immersed in background noise
Random matrix approach search signals immersed background noise
2011/10/17
We present new, original and alternative method for searching signals coded in noisy data. The method is based on the properties of random matrix eigenvalue spectra. First, we describe general ideas a...
