摘要： The invention provides a method of time slot synchronization in a mobile terminal and the apparatus therefor. The apparatus first acquires a coarse time parameter of a midamble in a time slot of a signal received by the mobile terminal. Then it performs correlation calculation of specific signal sequences in a sequence that conforms to the midamble and their respective corresponding specific signal sequences based on the coarse time parameter. In the end, the apparatus compares the results of said correlation calculation to determine an accurate time parameter of the midamble, thus achieving time slot synchronization. Using this method and apparatus the complexity of correlation calculation and the corresponding hardware cost can be reduced.

摘要： Abstract Nowadays big data is widely adopted in industry field. In an advanced manufacturing system hundreds of sensors are deployed to collect key variables for system performance and the real-time data would be used for further monitoring and anomaly detection. However, there are many challenges for applying the sensor-based data directly, including the time series data has unsynchronized different length for different samples, the existence of obvious systematic drift, strong correlation of sensor clusters and the particular feature extraction. To solve these problems this invention presents a multiple time series based engineering data processing system, including (1) preprocessing the signals to align the data and remove systematic drift, (2) clustering the sensors which have strong correlations, and (3) extracting particular features from different sensor clusters.
