Lorenz chaotic signal generator

The invention provides a Lorenz chaotic signal generator based on a signal encryption communication system. The Lorenz chaotic signal generator is based on a Lorenz system, and comprises an X signal generation module, a Y signal generation module and a Z signal generation module which are inside the Lorenz chaotic signal generator, wherein the X signal generation module comprises a reverse phase adder and a reverse phase integrator; the Y signal generation module comprises a phase reverser, a multiplier and a reverse phase integral adder; and the Z signal generation module comprises a multiplier and a reverse phase integral adder. The Lorenz chaotic signal generator has the advantages that parameters can be adjusted independently, the signal generator is convenient to use, programming is not needed, the process is simple, a single chip is not needed, and costs are low.
