  • DSP-based variable aperture code generation technique
    Patent number: 7042959
    Abstract: Variable Aperture Coded (VAC) signals for VAC modulation are advantageously generated by a digital signal processor (12) that yields a VAC signal having a single narrow peak in the positive frequency region. A Discrete-Time Hilbert transformer (12) isolates only the positive spectral peaks, thus yielding a VAC signal that affords greater control over zero crossings.
    Type: Grant

    Date of Patent: May 9, 2006
    Assignee: Thomson Licensing
