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.

摘要:
A method, a network base station, and a user communication device for transmitting data on an orthogonal frequency-division multiple access system are disclosed. A network base station may have a common antenna set to transmit on a subcarrier via a first effective channel able to be constructed based on at least one common reference symbol. The network base station may have a dedicated antenna set to transmit on a subcarrier via a second effective channel able to be estimated based on at least one dedicated reference symbol. The user equipment may demodulate a data transmission using the at least one common reference symbol and the at least one dedicated reference symbol.
摘要:
A method of signaling particular types of resource elements in a wireless communication system is disclosed. The method can include, at a wireless terminal, receiving (610) a message providing information of a set of allocated resource elements carrying data intended for the wireless terminal. The method can include receiving (620) an indication corresponding to a resource element of a particular type within the set of allocated resource elements. The method can include decoding (630) resource elements that carry data intended for the wireless terminal based on the message providing information and based on the indication.
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.
