N2 - 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, equivalent to Gold codes. This system
capitalizes on complex nonlinear dynamics afforded by multiscroll
chaos to provide higher security than conventional codes
with the same BER performance demonstrated experimentally
on a Xilinx Virtex 4 FPGA with logic utilization less than 1.25%
and throughput up to 10.92 Gbits/s.
