  • Patent number: 10348542
    Abstract: A method and apparatus for improving channel estimation within an OFDM communication system. Channel estimation in OFDM is usually performed with the aid of pilot symbols. The pilot symbols are typically spaced in time and frequency. The set of frequencies and times at which pilot symbols are inserted is referred to as a pilot pattern. In some cases, the pilot pattern is a diagonal-shaped lattice, either regular or irregular. The method first interpolates in the direction of larger coherence (time or frequency). Using these measurements, the density of pilot symbols in the direction of faster change will be increased thereby improving channel estimation without increasing overhead. As such, the results of the first interpolating step can then be used to assist the interpolation in the dimension of smaller coherence (time or frequency).

  • Patent number: 10341413
    Abstract: Provided are a method and system for synchronizing a robot with a server. The service sends a time service command including a current time of the server to the robot, and the robot receives the time service command, so as to enable time synchronization of the robot with the server. A control device receives first command data carrying a first timestamp sent from the server, and then determines whether the first timestamp in the first command data has expired. If the first timestamp has expired, the control device receives command data resent from the server until second command data carrying an unexpired second timestamp is received. Finally, the control device controls the robot to execute a corresponding action at a time corresponding to the second timestamp based on the second command data, so as to realize the synchronization of the robot with the command data sent from the server.

  • Publication number: 20190180135
    Abstract: Techniques are disclosed for extracting micro-features at a pixel-level based on characteristics of one or more images. Importantly, the extraction is unsupervised, i.e., performed independent of any training data that defines particular objects, allowing a behavior-recognition system to forgo a training phase and for object classification to proceed without being constrained by specific object definitions. A micro-feature extractor that does not require training data is adaptive and self-trains while performing the extraction. The extracted micro-features are represented as a micro-feature vector that may be input to a micro-classifier which groups objects into object type clusters based on the micro-feature vectors.
