  • VESTIGIAL PHASE SHIFT KEYING MODULATION AND SYSTEMS AND METHODS INCORPORATING SAME
    Publication number: 20120213521
    Abstract: In general, optical communication systems and methods may implement a vestigial phase shift keying (PSK) modulation format to enable relatively high transmission rates with closer channel spacing and improved signal detection in a WDM optical communication system. A PSK modulated signal may be correlated with a phase shift, for example, using a delay line interferometer (DLI), to generate a vestigial PSK signal, which may be pre-filtered, combined, and transmitted in the WDM system. The correlation with a phase shift compresses and shifts the signal spectrum such that intersymbol interference (ISI) length may be reduced with minimal increase in the bit error rate (BER) when the vestigial PSK signal is detected.

  • Method and apparatus for providing context-sensitive community links
    Patent number: 7822619
    Abstract: One embodiment of the present invention provides a system that provides a context-sensitive “community link,” which enables a system or application user to easily access a community forum related to a specific system or application feature. During operation, the system provides a user with access to the system or application feature. While providing such access, the system displays a community link to the user, wherein the community link is directed to a community forum associated with the system or application feature. When the user selects the community link, the system navigates the user to the community forum associated with the system or application feature, so that the user can exchange information with other users about the system or application feature.
