    摘要: Systems and methods for time synchronization of orthogonal frequency-division multiplexing (OFDM)-based communications are disclosed. A cyclic prefix (CP) correlation-based timing synchronization method is disclosed for early path (e.g. first-received path) detection for OFDM-based communication. Systems and methods are disclosed for performing double peak value detection in an OFDM-based system for reliably detecting an early (e.g., first-received) path in a received OFDM symbol for use in timing synchronization. In the double peak value detection method, a first peak value detection is performed to detect the path with the largest power, and a second peak value detection is then performed to detect a desired early (e.g., first-received) path. A compensation linear curve is used to facilitate the second peak value detection.

    摘要: A software architecture, design and implementation that enables efficient transistor performance analysis across multiple levels of parameter granularity with interactive drill-down, drill-across capability, for use during semiconductor technology development. The software may include several features, such as highly modular, robust architecture to enable analysis across the multiple granularity of transistor performance data, i.e., per die, material group, and aggregate, GUI-based template configuration to specify the analysis across the multiple levels in a uniform set of operations, subsystems to execute the template specified with the GUI, integration of pass-fail analysis analytics, interactive drill-down on particular data points of user interest in automatically generated charts, and drill-across capability allowing linking of data points highlighted on a single chart to those that are correlated in all other charts. Other embodiments are described.

    摘要: A system for conducting transistor performance analysis is disclosed, in which automatic graph plotting is interactively enhanced with human judgment. The system includes executing transistor performance analysis software, which receives templates specifying parameters, graph charting options, and algorithms, as well as a database of transistor values, as its inputs. The software produces an output document with linked graphs and a summary report. The software extracts, filters and applies statistical regression to large quantities of data. The software also applies statistical filtering to the data and automatically plots hundreds of charts and graphs based on the data. Graphs are color-coded to highlight relationships that suffer from unusually high noise in the data. Users can manually adjust lines on the graphs, which are automatically reflected in dependent graphs and the summary report. Changes to program methodology can be achieved by changing the template rather than by modifying the software.
