摘要： In a wireless communication system, a scheduler (100) determines (306) a first set of modulation and coding schemes (MCSs), each of which produces a maximum data rate for a first user, in accordance with available resource constraints (304) of the wireless communication system. The scheduler then forms, for each MCS of the first set, a second set of MCSs that produces the maximum data rate for a second user in accordance with a first residual resource (314) that remains when applying that MCS to the first user, thereby producing (316) a group of second sets of MCSs. After producing the group of second sets, the scheduler selects (324), from the first set and for the first user, a first optimal MCS corresponding to one of the group of second sets that allows a highest maximum data rate for the second user.

摘要： A method (1700) and apparatus (1801) provide channel estimation with extended bandwidth filters. Antenna (1813) receives a signal such as a pilot signal and detects a bandwidth associated with the pilot signal in a detector (320). One of a plurality of filters (603, 605, 607, and 609) including extended bandwidth filters (311) and a default filter (305) can be selected by a selector (617). If the detector detects activity associated with a wider bandwidth, the filter associated with the wider bandwidth is selected over the presently selected filter. If no activity is detected, the default filter is selected.

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.

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： An apparatus and method provides channel phase compensation for a digital radio frequency RF channel, by analyzing a demodulated signal (24) communicated over the digital RF channel and generates data representing an estimate of a channel phase (28), based on channel symbol reliability data (242) generated for at least one channel symbol received over the RF channel. The apparatus and method iteratively generates channel symbol reliability data (242) for a same symbol until a frame containing the symbol is determined to either pass a frame error threshold or until a predetermined number of iterations of channel phase estimates for a symbol is detected.

摘要： A timing recovery loop includes a sampler, a narrow band filter, an RMS normalizer, a timing error detector, and a sample controller. The sampler samples a received signal. The narrow band filter filters the sampled received signal so as to pass an upper band edge of the received signal and not a lower band edge of the received signal. The RMS normalizer sets an average power level of an output of the filter to a substantially constant value. The timing error detector detects a timing error with respect to an output of the RMS normalizer. The sample controller controls the sampler in response to the detected timing error.
