... fading channels. In [6] the authors investigated the use of eighth-order CCs to classify digital signals in a flat fading channel. By employing a multiantenna receiver using selection combining (SC), ... to determine a signal s modulation family in a slow 20-path fading channel using SC. carrier frequency, carrier phase, and symbol rate. By using lower-order cyclic statis...

... different points can become more similar after invariance regularization. In this way, we must also restrain invariance since a big increase in the degree of invariance may remove information ... isolated points, and tends to increase the density of points within segmented regions. We show in the last row of Figure 16 that as can be expected when using prior modeling, on certain occasi...
