Claim One:
1. A method of processing an aggregate data signal in wireless transmission, comprising: a. receiving an aggregate data signal at a receiving side, the aggregate data signal having a plurality of distinct data signals containing distinct user data signals originating from a plurality of users, wherein each one of the plurality of distinct data signals is modulated with a distinct chaos sequence at a transmitting side, and b. demodulating the each one of the plurality of distinct data signal at the receiving side to extract the distinct user data signals, the modulating of the each one of the plurality of data signals being performed using a generated digital chaos sequence database containing the distinct chaos sequence, wherein the generating of the distinct digital chaos sequence comprises, recording a featureless waveform having nonlinear dynamics, sampling a fixed number of samples for a particular spreading factor, storing a varied quantity of groups of the fixed number of samples for a particular spreading factor to form the entries of the database, such that the groups of fixed number of samples for a particular spreading factor are distinct with low cross-correlation amongst the groups, and then processing all the groups segments using Gram-Schmidt process.
