Patent ID: 8457077

Claim:
A method for code-division multiplex communications, comprising the steps of: forming a plurality of orthogonal or statistically orthogonal chaotic spreading sequences, each comprising a different chaotic sequence; generating at least one offset chaotic spreading sequence which is the same as a first one of said orthogonal or statistically orthogonal chaotic spreading sequences, but temporally offset by an amount defined by a remainder of division of a first number by a second number, where the remainder is computed via a modular division operation, the first number represents a number of cycles of a chaotic sequence generation offset from a reference time, and the second number represents a cycle in which each component of a chaotic sequence starts to repeat; forming a plurality of first spread spectrum communications signals, each respectively generated using one of said plurality of orthogonal or statistically orthogonal chaotic spreading sequences; forming at least one second spread spectrum communication signal using said at least one offset chaotic spreading sequence; and concurrently transmitting said plurality of first spread spectrum communications signals and said second spread spectrum communication signal over a common RF frequency band.
