... of a multicellular network. In a propaga- tion environment subject only to path loss and multi- path Rayleigh fading, we have established an accurate Figure 12 Empirical laws h, a, k, and b as ... single-interferer scenario, fluctuations of actual path losses G pl,n (r n ), n = 7, , 18, can be assumed to have about the same dynamic range, but these dynamics are smaller than those...

... here, a Volterra modelization happens to be only suitable for the task of identification and not for a direct equalization. For instance, a method based on a Volterra modelization of the TWT amplifier ... entropy of weights quantifies the information of the samples and measures the efficiency of representation for a given popu- lation of particles. This approach is ad...

... states that can lead the system to a specific attractor is called the basin of attrac- tion. There can be one or many states for each attractor. An attractor having only one state is called a ... average case. Therefore, this paper studies algorithms for identifying sin- gleton attractors that are fast in many practical cases and have concrete theoretical backg rounds. Some studies...
