A nonlinear dynamic system for spread spectrum code generation and acquisition

摘要: Nonlinear dynamic systems for generating and acquiring a spread spectrum signal pseudo-random noise (PN) are disclosed. An actuating is delayed by first second period to produce signals. A continuous, nonlinear function applied input that corresponds the signals an output signal. The has values correspond binary integer of mod 2 addition linear feedback shift register, non-zero slope at those values. becomes PN over time when it fed back synchronizes with reference superposed on system may be incorporated into transmitter or receiver, either which part larger communication system.
