摘要： A turbo decoder system utilizing a MAP decoding algorithm has a predetermined number of turbo decoder modules for decoding segments of a turbo code component code word in parallel, thereby expanding the block-length and data rate capability of the turbo decoder. Upon completion of any half iteration of the MAP decoding algorithm, the a posteriori bit probability estimates are provided to an interleave/de-interleave-and-convert-data function block wherein they are re-ordered, segmented, used to modify the original received data samples, and provided back to the respective turbo decoder modules as input data samples for the systematic bits. Decoding continues in this manner until a predetermined number of half iterations is performed, and data decisions are made on the final a posteriori estimates.

摘要： A method and system for an automatic exposure control (AEC) arrangement for a matrix-addressed imaging panel having an array of sensors including use of localized regions of the imaging panel exhibiting capacitive coupling. In one embodiment, the matrix-addressed imaging panel includes one or more AEC electrode receptive field regions that provide a signal representative of exposure specific, respective AEC electrode receptive field regions. Additionally, in another embodiment, the imaging array includes data line signal monitoring regions in which capacitive coupling between electrodes in radiation sensors adjacent to the data line are read and processed to provide and AEC signal. In another embodiment, the imaging array includes both AEC electrode filed receptive regions and data line signal monitoring regions that are coupled to an AEC controller for control of the radiation source for the imaging array.

摘要： A programmable clock circuit generates a plurality of phase clock signals in correspondence with an associated control word programmed into a memory. Programmable clock circuit is implemented digitally in an application specific integrated circuit. Each phase clock signal is synchronized by a master clock signal which reduces signal jitter and improves phase signal accuracy.
