Circuits fully digital hardware implementation of 1-D 2D and 3D multiscroll chaos

Abhinav S. Mansingka, et al., "Secure Ds-CDMA spreading codes using fully digital multidimensional multiscroll chaos." In 2013 IEEE 56th International Midwest Symposium on Circuits and Systems (MWSCAS), 2013, 1334. This paper introduces a generalized fully digital hardware implementation of 1-D, 2-D and 3-D multiscroll chaos through sawtooth nonlinearities in a 3rd order ODE with the Euler approximation, wherein low-significance bits pass all NIST SP. 800-22 tests. The low-significance bits show good performance as spreading code for multiple-access DS-CDMA in AWGN and multipath environments
