Abstract
A system for pre-processing transmission sequences in a jammed environment. System a transmitter suitable for transmitting the synchronization preamble further comprising a pseudo noise generator suitable for running a non predictable pseudo random algorithm. Pseudo random algorithm is suitable for generating a codeword operable as a pointer indexed into a table of gold sequences. Pointer is suitable for selecting a pseudo random selection of gold sequences from the table of gold sequences. Pseudo random selection of gold sequences forms a synchronization preamble. Gold sequences are concatenated together to form the synchronization preamble. System further comprises a receiver configured to receive the transmitted synchronization preamble further comprising of a decryption key suitable for decrypting received synchronization preamble.
