  • Patent number: 8446931
    Abstract: Synchronization of a primary link which transitions between clear mode and spread mode is achieved and maintained using a secondary link. When transitioning from clear mode to spread mode, a primary transmission delta phase is adjusted by the difference between a secondary reception delta phase and the primary transmission delta phase; and a primary reception delta phase is adjusted to be equal to a secondary transmission delta phase.

  • Patent number: 7200233
    Abstract: A system for fast data encryption/decryption is provided. The system includes a transmitter system having a transmitter direct digital synthesizer (DDS). The DDS includes at least three transmitter pseudo-noise (PN) component code generators PNx, PNy, PNz, where each transmitter PN component code generator is adapted to generate relatively prime transmitter PN component codes when compared with each of the other transmitter PN component code generators. The transmitter also includes a first processor coupled to the transmitter DDS, where the first processor is adapted to determine a time slot number (TSN) relative to at least two of the relatively prime transmitter PN component codes. Also included in the transmitter is an encryptor for encrypting clear data in accordance with the TSN. The system includes a receiver system having a second processor adapted to determine the TSN; and a decryptor coupled to the second processor.

  • Patent number: 7167504
    Abstract: This invention generates pseudo-noise (PN) codes that map a transmitted data rate into the PN code structure. This invention further then acquires the PN code to automatically discover the transmitted data rate. This invention is operable with communication systems that utilize GPS time synchronization of the transmitted and received PN codes, as well as with communication systems where GPS time synchronization is not available. A method and a system are disclosed to transmit a modulated signal from a transmitter to a receiver, where the modulated signal has a data rate. The method includes selecting, to represent the data rate, at least one PN component code from a set of PN component codes. The PN component code is a constituent code of a composite PN code comprised of a plurality of PN component codes. The selected PN component code is one that phase aligns with a PN composite encoded signal.

  • Patent number: 7054350
    Abstract: A method and system for synchronizing the PN phase of a pseudo-noise (PN) coded signal with a phase of a master PN decade-code is provided. The method includes the steps of associating the master PN decade-code initialization t0 with a first time zone reference date and time and determining an elapsed time t1. The next steps equate the elapsed time t1 to a corresponding phase of the master PN code and synchronize the phase of the PN coded signal with the corresponding phase of the master PN decade-code.
