Latest Patents

Hsin-An Liu holds a patent for "All Digital Reference Frequency Locking." This patent describes an all-digital approach for operation within one or more cable modems (CMs) to lock the upstream of the CMs to the downstream symbol clock provided from a Cable Modem Termination System (CMTS). The locking process can be achieved through three different functions: locking the upstream symbol clock phase to the downstream symbol clock phase, locking the downstream symbol clock phase to the headend reference clock phase, and locking the upstream carrier frequency to the downstream symbol clock frequency. These all-digital techniques support high performance for S-CDMA and other synchronous modulation techniques.
