High instantaneous bandwidth auto-indexing parallelized chaotic waveform data modulator and demodulator with temporal automatic gain control, increased path diversity and sequence lock up prevention

A transmitter for a chaos communications system, said transmitter comprising:

• a symbol mapper that converts a series of information bits to a series of bit symbols;
• and
• at least one chaos generator providing a chaos sequence for each bit symbol, said at least one chaos modulator including a RAM/ROM that provides auto-indexing where a chaos sequence output from the RAM/ROM is fed back to an input of the RAM/ROM from which a chaos sequence at a next address in the RAM/ROM is selected as the output of the generator, wherein the RAM/ROM includes an additional column to the end of each RAM address that prevents chaos sequence lock up, the at least one chaos generator converts floating-point chaos sequences to fixed-point chaos sequences, and the transmitter further includes a temporal automatic gain controller (AGC) that controls the gain of the chaos sequence for transmission.

A method for communications comprising:

• converting a series of information bits to a series of bit symbols;
• and
• generating a chaotic sequence for transmission for each bit symbol that includes auto-indexing where a chaos sequence output from a RAM/ROM is fed back to an input of the RAM/ROM from which a chaos sequence at a next address in the RAM/ROM is selected as the next chaotic sequence for the bit symbol.
