  • Publication number: 20250211337
    Abstract: Joint estimation of the framer index and the frequency offset in an optical communication system are described among various other features. A transmitter can transmit data frames using pilot and framer symbols. A receiver can estimate the framer index and frequency offset using the pilot and framer symbols, and identify the beginning of a header portion of a data frame. The estimation can be performed to compensate for delays such as half-symbol delays and differential group delays. By identifying the beginning of the header portion of a data frame while compensating for certain delays, the receiver can synchronize, with less error, the data transmitted by the transmitter and the data it received.

  • Patent number: 12137539
    Abstract: An electronic device heat dissipation system with a sugar alcohol PCM energy storage unit includes a cooling circulation pipeline, a heat dissipation cold plate, an energy storage heat exchanger, a crystal powder feeder, and a radiator. Fluid in the cooling circulation pipeline flows sequentially through the heat dissipation cold plate and the energy storage heat exchanger, and the fluid flowing out of the energy storage heat exchanger can optionally pass through the radiator. The energy storage heat exchanger is filled with a sugar alcohol PCM as an energy storage medium, the energy storage medium can absorb heat, melt, solidify and regenerate, and the crystal powder feeder input crystal powder of the energy storage medium to improve a solidification and regeneration speed of the energy storage medium. Heat storage capacity of the sugar alcohol PCM is used, combined with the radiator and the heat dissipation cold plate to achieve temperature control.

  • Patent number: 11757535
    Abstract: Optical transmitters and receivers for improving synchronization of data transmitted over an optical network are described. The receiver can perform non-linear filtering as part of framer index estimation operations to improve the synchronization. The receiver can determine estimated positions of framer indices in data frames received from the transmitter. Next, using a non-linear filter, the receiver can remove estimated positions that are likely erroneous or are greater than a threshold away from the median or mode estimated framer index position. By removing the likely erroneous estimated positions, the receiver can then determine the estimated position of a framer index position for multiple frames with greater confidence.

By identifying the beginning of the header portion of a data frame, the receiver can synchronize, with less error, the data transmitted by the transmitter and the data it received. To further improve the framer index estimation, a lock indicator signal can be generated to signal to other receiver components that the estimated framer indices are reliable. The receiver can determine frequency offset and additional framer index estimations with increased reliability when performed after the lock indicator signal is generated.
