Simulation and Characterization of an Exact Solvable Chaotic Oscillator and Matched Filter

Abstract

The simulation and characterization of a low frequency exact solvable chaotic oscillator and a corresponding matched filter is presented with discussion. The work builds on an existing design for the oscillator by realizing a version of the oscillator which performs analogously in both SPICE simulation and hardware for both shift-band and folded-band operation. Results from simulation and hardware are presented and compared to verify simulation accuracy.

SPICE simulation of the matched filter is also presented; its accuracy is verified by comparison to published theoretical behavior. This simulation is used to evaluate and characterize the frequency requirements of the matched filter's input. Use of the chaotic oscillator/matched filter pair in communication applications is supported by the results of this characterization.
