Voice and data privacy using chaotic time sequences

摘要

A voice and data privacy system which is both very secure, and a powerful error correction algorithm, is described. A convolved, random, chaotic sequence of impulses is used to transmit data along the channel. The resultant signal in the channel closely resembles gaussian random noise, yet it is confined to the same bandwidth as that of the original data. A second, complementary sequence of pseudorandom, chaotic impulses is then derived which deconvolves the data and returns it to a normal signal for demodulation. Privacy is assured by the unique nature of the random code, and trillions of codes are possible in a given channel. Errors are corrected by the bridging effect of the long sequence, and correction of as many as 100 errors in series has been demonstrated by using very long time sequences.
