In this study, to solve the hidden limitation of conventional weighted fractional Fourier transform (WFRFT), a random\nmodulation order parameter pool is established by applying chaos technology. Further, a WFRFTsecure communication method\nbased on the chaotic parameter pool (CPP) is proposed. Based on the effective characteristics of tent mapping and the sequence\noutput range, the parameter pool constructor is established by parameter transformation. Furthermore, for each parameter\nselection period, the information can be processed by WFRFT using different modulation orders. The modeling and simulation\ndemonstrate that this method can significantly increase the bit error rate and processing time of unauthorized receivers. This\nindicates that it can greatly increase the scanning difficulty of unauthorized users and improve the concealment and security of the\noriginal information transmission.
