With the growing concern over energy consumption, green communication is becoming more and more important. Lots of efforts have been put into investigating in energy-efficient wireless systems. Since Fractional Frequency Reuse (FFR) is a widely-used Inter-cell-interference coordination scheme in the ...
For a chaotic system, the higher the complexity is, the higher the randomness of the pseudo random sequence generated by the chaotic system is, so it is more conducive to be applied to chaotic secure communication. For calculating the complexity of the proposed fractional-order chaotic maps, a...
due to individual conformity during the communication exchange process between the individual and population during an iterative search, the standard PSO technique may reduce population diversity and limit the solution to particular local optimization points, failing to obtain global optimization70. The algo...
