SMETHODS FOR REDUCING THE PAPR OF FBMC SIGNALS BASED ON A DISCRETE-NONLINEAR SPROTT SYSTEM IMPLEMENTED OVER A FINITE GALOIS FIELD

In this article, we provide a comparative analysis of various methods for reducing the peak factor of Filter bank Multicarrier signals in a multiplexing system with a filter bank using the discrete-nonlinear Sprott system implemented over a finite Galois field. The methods of partial transmission sequence, scrambling, and a combined method, which includes both methods, are considered. Each method is based on the use of a pseudorandom sequence, the formation of which is provided by generators based on a discrete nonlinear Sprott system. As a result of the work, the peak factor for each method is estimated and an additional cumulative distribution function is also presented. In addition, the influence of the number of iterations and windows used in the partial transmission sequence method on the peak factor was estimated. The results obtained in the course of the study can be applied in the design of information transmission systems.
