  • Patent number: 10749633
    Abstract: Polar codes may be generated with a variable block length utilizing puncturing. Some puncturing schemes consider punctured bits as unknown bits, and set the log likelihood ratio (LLR) for those bits to zero; while other puncturing schemes consider punctured bits as known bits, and set the LLR for those bits to infinity. Each of these puncturing schemes has been observed to provide benefits over the other under different circumstances, especially corresponding to different coding rates or different signal to noise ratio (SNR). According to aspects of the present disclosure, both puncturing schemes are compared, and the puncturing scheme resulting in the better performance is utilized for transmission.

  • Publication number: 20200239351
    Abstract: Articles and methods related to the cold-forming of glass laminate articles utilizing stress prediction analysis are provided. A cold-forming estimator (CFE) value that is related to the stress experienced by a glass sheet of a glass laminate during cold-forming is calculated based on a plurality of geometric parameters of glass layer(s) of a glass laminate article. The calculated CFE value is compared to a cold-forming threshold related to the probability that defects are formed in the complexly curved glass laminate article during cold-forming. Cold-formed glass laminate articles are also provided having geometric parameters such that the CFE value is below the cold-forming threshold.

  • Publication number: 20190342847
    Abstract: Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EUTRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for PDSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and PDSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells.
