  • Patent number: 10911178
    Abstract: Systems and methods for blind detection of a numerology of a received signal are described. In one aspect, a method is provided for a user equipment (UE) to blindly detect the numerology of a received signal. The method includes correlating cyclic prefix (CP) signals in the received signal in the time domain based on a plurality of hypotheses of subcarrier spacing (SCS) and determining a numerology of the received signal for a corresponding hypothesis of SCS of the plurality of hypotheses based on the correlated CP signals.

  • Publication number: 20050244005
    Abstract: Methods and systems enable content authors to achieve frame-accurate editing and, in at least some embodiments, reduce the amount of content that needs to be decompressed in order to operate on the frames. Some embodiments ensure that bit rate integrity is preserved so that bit rate conditions associated with streaming environments are preserved. Various embodiments intelligently determine which content portions should be decompressed, processed, and recompressed and which content portions should not be decompressed.
