In this paper, the feasibility of replacing a chaos source by an equivalent digital pseudo-random generator realized using Linear Feedback Shift Register (LFSR) is studied. Particular emphasis is given on the digital implementation Piece-Wise Linear Affine Maps (PWAM). As an application, an FPGA implementation of four different maps has been experimentally verified in a FM-DCSK test radio system.
