  • Method and apparatus for transmitting or detecting a primary synchronization signal
    Patent number: 10057003
    Abstract: A method and apparatus for transmitting or detecting primary synchronization signal. The receiver receives primary synchronization signal from a transmitter, and detects the sequence used in the received primary synchronization signal by using three root indexes. Here, the primary synchronization signal is generated by using a Zadoff-Chu sequence having one of the three root indexes. The three root indexes comprise a first index and a second index, and a sum of the first index and the second index corresponds to the length of the Zadoff-Chu sequence.

  • APPARATUS AND METHOD FOR PROCESSING CONTENT
    Publication number: 20180197094
    Abstract: A content processing apparatus and method is provided, in which content input by a user is processed by determining whether transmission of the content corresponds to an abnormal pattern when a relation between the user and the other party is taken into account, and for automatically adjusting a permissible level by learning whether the content is an abnormal pattern based on the user's response. The content processing apparatus can estimate whether the content corresponds to an abnormal pattern by using a rule-based algorithm or an artificial intelligence (AI) algorithm when determining whether the content corresponds to the abnormal pattern. When determining whether the content corresponds to the abnormal pattern is estimated using the AI algorithm, the content processing apparatus can use machine learning, a neural network algorithm, or a deep learning algorithm.
