1. A method for communicating a sequence of information symbols between a transmitter and a receiver using a chaotic sequence spread spectrum signal, the method comprising:

  • generating identical sequences of chaotic chips at said transmitter and said receiver, said sequences of chips synchronized in time;

    transmitting a sequence of information symbols in signal using said sequence of chips generated at said transmitter, each of said information symbols in said signal having a variable duration of transmission based on a threshold symbol energy value and said chips generated at said transmitter;

    extracting said sequence of information symbols from said transmitted signal, each of said information symbols in said transmitted signal extracted using said chips generated at said receiver and said threshold symbol energy value;

    wherein said duration of transmission of each of said information symbols in said signal is a total duration of a selected number of said chips used for transmitting each information symbols, and wherein said number of said chips is selected for each of said information symbols to provide a total chip energy that is greater than or equal to said threshold symbol energy value.
