  • Fine timing
    Patent number: 9973368
    Abstract: A fine timing method is provided. The method comprises: calculating values of a first timing metric function based on cross-correlation between a received signal and M training sequences within a time period, to obtain a plurality of sets of X values spaced according to a certain pattern; calculating summations for the plurality of sets of X values, respectively; and determining the beginning of a data frame based on the calculated summations.
    Type: Grant
    Filed: August 12, 2013
    Date of Patent: May 15, 2018
    Assignee: Harman Internatioanl Industries, Incorporated
    Inventors: Wenjiang Pei, Jinguang Hao, Kai Wang, Zeng Yang
  • Transformation between time domain and frequency domain based on nearly orthogonal filter banks
    Patent number: 9871685
    Abstract: A filter bank for signal decomposition is provided. The filter bank comprises a plurality of filter units each of which has one input and two outputs forming two paths whose transfer functions are complementary to each other, where the plurality of filter units are connected to form a tree structure.
    Type: Grant

  • Coarse timing
    Patent number: 9787517
    Abstract: A coarse timing method for a communication system is provided. The coarse timing method may include: calculating timing metric values for received signal samples using a self-correlation based timing metric function; calculating average timing metric values based on previous timing metric values; and determining whether there is a data frame based on the timing metric values and the average timing metric values.
