摘要： A method and system are described herein that a employ a lost frame concealment technique for processing data frames received during transmission over a communications channel. The lost frame concealment technique involves determining whether a current data frame is a bad frame, performing source decoding on the current data frame with one or more parameters that are limited by a first set of one or more values if the current data frame is a bad frame, and performing source decoding on the current data frame with one or more parameters that are not limited if the current data frame is a good frame.

摘要： Methods and apparatus for cataloguing items such as maps and geospatial data sets store in a database information defining a geospatial region corresponding to each item and a size characteristic of the geospatial area. The database may be queried to identify items of interest by intersecting a search seed comprising one or more geospatial points lines or areas with the areas corresponding to the items. A result set containing items produced by a query may be ordered at least in part according to the size characteristics. In some embodiments the size characteristics comprise square roots of the areas of the geospatial regions.

摘要： Receivers and methods are provided that include multiple modes of processing signals from multiple antennas. These include legacy, SAIC (single antenna interference cancellation) and MSRD. Various methods are provided for selecting an appropriate receiver processing function. These include looking at correlation and gain imbalance between antennas, looking at the processing gain resulting from one or more of the receiver processing functions, and looking at the equalization quality of at least two receiver processing functions.

摘要： Apparatus and method for allocating communication resources in a data radio communication system, such as an MAIO (Mobile Allocation Index Offset) communication system, e.g., a communication system that provides for Enhanced Data for GSM Evolution (EDGE) data services. A multi-carrier radio resource control logic element includes an analyzer that analyzes communication resource requirements to carry out a communication service. A resource allocator allocates communication resources to be used by which to communicate the data. The communication resources are allocated across a plurality of radio carriers such that resources are allocated, during a particular time period, upon a single radio carrier of the plurality of radio carriers.

摘要： Apparatus, and an associated method, for estimating a bit error rate of data communicated to a receiving station of a digital communications system, such as a GSM/EDGE cellular communication system. Soft decision values, indicative of confidence levels that decided values have been correctly decided are compared with threshold values by a comparator. A count is accumulated by a counter to whose counted value is representative of decided data values having associated therewith low levels of confidence that the decided values are correct. The count value is used in the formulation of the BER estimation.

摘要： Apparatus, and an associated method, for a receiving station, such as the receive part of a mobile station, that has diversity antennas. The receiving station includes both legacy demodulators and a diversity demodulator. Calculations are made to determine signal indicia associated with the signal energy detected at the diversity antennas. Responsive to the signal indicia, selection is made as to whether to utilize demodulation data, demodulated pursuant to a diversity demodulation technique or pursuant to a legacy demodulation technique. As the characteristics of received signals change, reselection of the demodulation is correspondingly made, such as on a frame-by-frame basis of frame-formatted data.
