摘要： Methods and apparatus are described for mitigating intercell interference in wireless communication systems utilizing substantially the same operating frequency band across multiple neighboring coverage areas. The operating frequency band may be shared across multiple neighboring or otherwise adjacent cells, such as in a frequency reuse one configuration. The wireless communication system can synchronize one or more resource allocation regions or zones across the multiple base stations, and can coordinate a permutation type within each resource allocation zone. The base stations can coordinate a pilot configuration in each of a plurality of coordinated resource allocation regions. Subscriber stations can be assigned resources in a coordinated resource allocation region based on interference levels. A subscriber station can determine a channel estimate for each of multiple base stations in the coordinated resource allocation region to mitigate interference.

摘要： An image data addressing system for a digital image printer operates on a plurality of image data having a horizontal format. Ink jet type digital printers require the alignment of the image data in a horizontal fashion to accommodate the vertical, mechanical arrangement of the ink jet nozzles. A program adapted to the specific components, circuitry and other characteristics of the digital image printer performs data addressing on the image data for preparation for ink jet firing by the ink jet nozzles. A common, integrated memory is used to perform the image data processing of the plurality of image data. The digital image printer adaptable program governs the storing of the image data so that it is adaptable to the specific components, circuitry and other characteristics of the digital image printer. An unused, consecutive portion of the integrated memory is provided at certain times during the image data processing. In certain embodiments of the invention, the image data addressing system is contained within a multi-functional peripheral. The multi-functional peripheral device is a peripheral device containing several internal devices that operate either independently or cooperatively to perform image data processing. Alternatively, the image data addressing system is found in a stand alone device that performs primarily one single function, namely, image data addressing. Highly computationally intensive functions use the unused, consecutive portion of the integrated memory. One particular function that is highly computationally intensive is motor control within an ink jet digital image printer.

摘要： A printer that uses a number of control state machines to reconfigure logic array circuitry to perform image data processing in preparation for printing. The logic array circuitry is programmable and adaptable to accommodate a wide variety of printer components characteristic to digital image printing systems. The logic array circuitry is reconfigured, depending on the particular printer in which the invention is implemented, by the control state machines as they receive control state machine conditions corresponding to the printer components characteristic to that specific digital image printer. For example, the physical, mechanical, and electrical characteristics of the printer constitute the printer component that modify the control state machine conditions which in turn govern the configuration of the logic array circuitry through the control state machines. Examples of printer components used to determine the control state machine conditions include, among other things, the number of ink jet printer nozzles, the ink jet nozzle separation, the firing order of the ink jet nozzles, and other characteristics of the digital image printer including electrical processing circuitry characteristics of the digital image printer. Selected portions of the logic array of the printer is used to perform a variety of image data processing functions including, among other things, nozzle data shifting, nozzle data masking, nozzle dot counting, nozzle data mapping, and nozzle columns separation. Certain of these functions are performed using serial image data processing.

摘要： A digital image printer that performs bit rotation and row alignment in preparation for final image reproduction. The present invention combines the two digital image data processing functions of bit rotation and row alignment into a single functional step. The two functions are performed simultaneously, in that, while row alignment is being performed during the deposition of a portion of the digital image data into a certain portion of a group of memory buffers, bit rotation is performed by extracting another portion of the digital image data from another portion of a group of memory buffers. The present invention reduces the number of required digital image data memory buffers required to perform the two functions of bit rotation and row alignment from conventional systems that perform the two functions sequentially and utilize a direct memory access channel to perform the data transfer between integrated circuitry that performs the two functions. The present invention presents a design that is inherently scaleable to accommodate any variety of digital image printing systems having various mechanical and electrical characteristics. The present invention does not require any digital image data preprocessing by a host before receiving the digital image data in preparation for digital image reproduction.
