摘要： A handheld computing device comprises a data processor configured to allocate a set of measurements of a wireless signal amongst partitions of a hierarchical multi-level partition space. Each level has a plurality of the partitions. Each partition has a respective numerical range, and the value of each allocated measurement is within one of the ranges. One of the measurements allocated to one of the partitions has a desired rank. This partition encompasses the range of all the partitions in the immediately lower level. Each partition in the immediately lower level has a desired resolution for the allocated measurements. The data processor sums the number of measurements allocated to each respective partition in the immediately lower level until the desired rank is obtained. The numerical range of the partition in this lower level that is associated with the desired rank comprises an estimate of a characteristic of the wireless signal.

摘要： A filter for reducing co-channel interference within a communications receiver may include a multi-channel, space-time filter circuit that filters n signal parts that have been split from a communications signal by jointly estimating space-time filter weights and multi-channel impulse responses (CIRs). The filter may further include a multi-channel, matched filter circuit that receives multi-channel signals from the multi-channel, space-time filter circuit and has a filter response that is provided by a channel impulse response estimation from the space-time filter circuit.

摘要： A receiver for a mobile communication system includes a channel equalizer for receiving a burst and generating a soft decision output associated with the burst, a soft decision correction circuit follows the channel equalizer and a decoder receives and decodes a block of bursts. The soft decision correction circuit calculates a correction factor based on the soft decision output for the burst and applies the correction factor to the burst prior to the burst entering the decoder.

摘要： Apparatus, and an associated method, for facilitating synchronization of a mobile station with a radio network in a GSM/EDGE-compatible, cellular communication system. The FCCH is monitored to obtain positional and frequency offset information. Once obtained, the information is used to obtain SCH burst information broadcast upon an SCH. Monitoring of the FCCH continues while the SCH burst information is detected and decoded. If additional FCCH control information is detected that has an associated quality metric value that is better than the quality metric value associated with earlier FCCH, control information, the newly-received information is used to detect the SCH burst information, absent successful decoding of the SCH burst information.

摘要： There are described tools and methodologies for building Read Only Memory (ROM) mask software images and the corresponding data/code patching software images. One method is for creating ROM mask content having patch references included therein whereby patch reference errors are detected and corrected. A software patch for a ROM mask with existing patch references may then automatically be created.

摘要： The present invention relates to surfacing material which may emit radiation in response to exposure to a given light source. Such surfacing material may be polymeric based, and e.g., fiber based, and may be used in relatively low-light areas, including low-light areas as applied to vehicular applications. The fiber-based or molded materials may emit radiation in response to exposure to a selected light source and may be used in relatively dimly lit areas. The materials may also provide a visible contrast to other objects located adjacent their surface which do not emit radiation. Optical brighteners and luminous particles may be included in the materials to make them luminous.
