摘要： Power control bit generation for forward link power control in a spread spectrum communication system is accomplished through modification of a set point threshold. Modification of the set point reduces the number of squaring and division mathematical operations, thus more efficiently utilizing limited system resources in a mobile receiver used in forward link power control.

摘要： A decoding method and apparatus performs a forward recursion process on recursive convolutionally generated symbols and performs backward recursion on the symbols wherein a next state for the backward recursion process is based on linearly combining both a plurality of bits defining a current state of a backward recursion process and a hypothesized information bit. In one embodiment, a backward state determinator (200) combines all binary bits in a current state backward recursion register (202) to generate a most significant bit (MSB) (210) of a next state backward recursion register (204). To obtain remaining bits of the next state backward recursion register (204), bits (207a-207n) in the current state backward recursion register (202) are shifted. The shifted bits then serve as the least significant bits (208a-208n) in the next state backward recursion register (204). Accordingly, a suitable linear combination and bit shifting approach is used to determine the content of a next state backward recursion register (204).

摘要： A system and method provide functionality for collecting user update reports of geographic inconsistencies between geographic data and the real world to enable automated processing of updates to the geographic data. A user's input is collected and describes an anomaly, which is a geographic inconsistency between geographic data and the real world. The user's input is stored as language neutral structured data that enables automated processing of updates to the geographic data. Automatic processes that process the structured data include an email agent, an incident agent, a geographic augmentation agent, a case generation agent, a clustering agent, an automatic validation agent, and a monitoring service. Automatic and manual processes combined together handle processing of anomalies, as well as other related processing, and ultimately handle processing of updates to the geographic data to resolve the anomalies reported by the users.
