  • Patent number: 10917864
    Abstract: The invention relates to the technical field of communications, and more particularly, to a method and device for realizing synchronization. The method comprises: performing, by a base station, and according to an SRS signal transmitted by a terminal, filtering to obtain a RRU channel having the maximum receiving power in a current operation; upon determining that the RRU channel having the maximum receiving power in the current operation is different from a RRU channel used in the currently performed demodulation, refraining from performing immediate switching; and permitting switching of the RRU channel only when the receiving power of the RRU channel is determined to match the maximum threshold of a preset series of thresholds, and transmitting a TA command word to the terminal while switching the RRU channel to complete synchronization with the terminal. The invention prevents a terminal from frequently switching between RRU channels on a subframe basis.

  • Patent number: 10885900
    Abstract: Improvements in speech recognition in a new domain are provided via the student/teacher training of models for different speech domains. A student model for a new domain is created based on the teacher model trained in an existing domain. The student model is trained in parallel to the operation of the teacher model, with inputs in the new and existing domains respectfully, to develop a neural network that is adapted to recognize speech in the new domain. The data in the new domain may exclude transcription labels but rather are parallelized with the data analyzed in the existing domain analyzed by the teacher model. The outputs from the teacher model are compared with the outputs of the student model and the differences are used to adjust the parameters of the student model to better recognize speech in the second domain.
