Chaotic property of almost periodic frequency arrangement (APFA)

抄録

We propose an almost periodic frequency arrangement (APFA) constructed by an irrational number group created using the power root of a prime number. Based on findings, it is possible to connect more than one million channels at a base station using the super-multicarrier APFA systems with the same communication quality characteristics as the current system. In this paper, we propose a new frame Lyapunov exponent (FLE) which estimates the phase difference sensitivity depending on the frame number. We reveal the universal feature of FLE and elucidate several characteristics such as short-term radiations of phases.
