Abstract: An anti-interference signal detection and synchronization method for a wireless broadband communication system. The method uses the peak value of a cross-correlation value of a received signal and a local sequence as a basis for determining signal detection and system synchronization. Because the cross-correlation value of the received signal and the local sequence is less affected by a signal-to-noise ratio and interference signals, the method can adapt to signal changes, can effectively alleviate the frame loss problem of a received signal autocorrelation based scheme under a low signal-to-noise ratio and interference condition, and also has good anti-noise and anti-interference capabilities.

Abstract: The present application provides text address processing methods and apparatuses. Some method embodiments include: determining, according to social relation circles of users in a service system, at least one address set, each address set including at least two original text addresses; and performing, for each address set, normalization processing on original text addresses in the address set, to obtain a target text address corresponding to the address set. Some embodiments of the present application divides to-be-normalized original text addresses according to social relation circles of users, which, on one hand, is equivalent to reducing the range of the to-be-normalized original text addresses, and on the other hand, is equivalent to locking the normalization of text addresses between text addresses having an association. Therefore, it may be easier to control a fault-tolerant boundary between the text addresses, and may be conducive to improving accuracy of the normalization result.

Abstract: The available delivery capability (ADC) of a power distribution network with respect to a power transaction is evaluated in real-time. The power transaction involves simultaneous power deliveries from power sources in a source area to loads in a sink area. First, a list of contingencies are ranked in the power distribution network with respect to static security constraints to obtain a subset of top-ranked contingencies. For each top-ranked contingency in the subset, a representation of the power transaction in a steady state of the power distribution network, in a form of parameterized three-phase power flow equations, is solved to obtain a corresponding power delivery capability (PDC) and a corresponding binding constraint among the static security constraints. The reliability of the power transaction in the power distribution network is then evaluated based on, at least in part, a first contingency PDC which is a smallest PDC among obtained corresponding PDCs.
