  • Patent number: 10804982
    Abstract: Communication systems and methods in accordance with various embodiments of the invention utilize modulation on zeros. Carrier frequency offsets (CFO) can result in an unknown rotation of all zeros of a received signal's z-transform. Therefore, a binary MOCZ scheme (BMOCZ) can be utilized in which the modulated binary data is encoded using a cycling register code (e.g. CPC or ACPC), enabling receivers to determine cyclic shifts in the BMOCZ symbol resulting from a CFO. Receivers in accordance with several embodiments of the invention include decoders capable of decoding information bits from received discrete-time baseband signals by: estimating a timing offset for the received signal; determining a plurality of zeros of a z-transform of the received symbol; identifying zeros from the plurality of zeros that encode received bits by correcting fractional rotations resulting from the CFO; and decoding information bits based upon the received bits using a cycling register code.

  • Patent number: 10797920
    Abstract: System for generating a constant envelope and suppressed cyclic feature signal may include a transmission security (TRANSEC) function, a spread spectrum chip, an M-ary continuous phase modulator, and a pulse-shaped filter. The TRANSEC may generate a pseudorandom symbol by M-ary symbol generation selects a symbol with a signal phase, and the spread spectrum chip corresponding to the generated pseudorandom symbol or a phase rotation of the pseudorandom symbol. The M-ary continuous phase modulator with a delta-phase mapper maps the signal phase based at least in part on the selected symbol. The pulse-shaped filter of the M-ary modulator introduces inter-symbol interference from a previous and a subsequent symbol into a current symbol; the inter-symbol interference may be introduced by the main lobe of the signal phase being contained within a bandwidth of a chip rate of the spread spectrum chip for frequency modulation signal transmission of information by the generated signal.
