Abstract:
1. A method for generating an adaptive PAPR chaotic communication signal, comprising: phase modulating a carrier signal with data to form an information signal; generating a chaotic spreading sequence based on a chaotic number sequence, said chaotic spreading sequence having a magnitude that is constant and having a variable arbitrary phase angle comprising phase values which are uniformly distributed over a predetermined range of angles; forming a spread spectrum signal by multiplying said information signal by said chaotic spreading sequence, said spread spectrum signal having a constant amplitude and a zero autocorrelation; detecting current operating conditions of a communication environment; and dynamically transforming said spread spectrum signal with a first PAPR to a chaotic signal with a second PAPR having a higher value than the first PAPR, based on said current operating conditions of the communication environment.
