Patent ID: 8351484

Claim:
A method for code-division multiplex communications, comprising the steps of: generating a plurality of orthogonal or statistically orthogonal chaotic spreading codes having different static offsets using a set of modular polynomial equations of a third order or higher, where at least two polynomial equations of said set of modular polynomial equations differ with respect to polynomial degree; forming a plurality of spread spectrum communications signals respectively using said plurality of orthogonal or statistically orthogonal chaotic spreading codes; and concurrently transmitting said plurality of spread spectrum communications signals over a common RF frequency band; wherein each spreading code of said plurality of orthogonal or statistically orthogonal chaotic spreading codes is generated using a different acc-dec value for a variable “v” of said modular polynomial equations, where v is a variable defined by a modular arithmetic equation and has a value selected to advance or regress a chaotic sequence generation by at least one cycle.
