Patent ID: 8369377

Claim:
A method for providing communications link with a power-limited communication transmitter positioned remotely from an intended receiver system, where said communication link is resistant to natural and artificial sources of interference, said method comprising: channel encoding a carrier signal with data provided at said power-limited communication transmitter 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 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 an adaptable amplitude characteristic and a zero autocorrelation; detecting current operating conditions of a communication environment; dynamically transforming said spread spectrum signal with a first peak to average power ratio (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; and transmitting said chaotic signal from said power-limited communication transmitter to said intended receiver system.
