  • Modular carrier recovery
    Patent number: 11637638
    Abstract: A method at a receiver comprises receiving a signal conveying symbols at respective positions within a clock cycle, the symbols comprising a data set consisting of data symbols and a pilot set consisting of pilot symbols; determining detected phases of the symbols based on the signal; generating first phase estimates based on the detected phases of a subset of the pilot set, and reference phases of the subset of the pilot set, the first phase estimates being associated with the positions of the pilot set; and generating second phase estimates based on the detected phases of the pilot set, reference phases of the pilot set, and the first phase estimates, the second phase estimates being associated with the positions of the pilot set and of at least a subset of the data set; and applying rotations to the detected phases of the symbols based on the second phase estimates.
    Type: Grant

  • Methods and apparatus to perform antenna management
    Patent number: 8687601
    Abstract: Methods and apparatus to perform antenna management are described herein. One example method of establishing communication between user equipment and a network includes receiving a control channel message, decoding the control channel message, and sending an indication of whether interoperability of receiving signals from a first number of antennas is certified for the user equipment. Other examples are shown and described.
