    Abstract: k input bits are encoded according to a code with which is associated a m x n=m+k parity check matrix H. The resulting codeword is punctured, with n' bits. The punctured codeword is exported to a corrupting medium such as a communication channel or a memory. A representation of the punctured codeword is imported from the corrupting medium and is decoded using a matrix H' that is smaller than H. For example, H' is m'=m~(n-n ') x n' and is derived by merging selected rows of H. Alternatively, H has at most m rows and fewer than n columns but more than n' columns. Alternatively, H has fewer than m'=m-(n-n') rows and fewer than n' columns.

    Abstract: Systems and methodologies are described herein that facilitate processing and pruning of blind decoding results (e.g., associated with grant signaling) within a wireless communication environment. As described herein, blind decoding results associated with grant signaling and/or other suitable signaling can be pruned in various manners, thereby reducing false alarm probabilities associated with such results. For example, techniques are provided herein for constraining respective decoding candidates to possible radio network temporary identifier (RNTI) values, performing validity checking on payload of respective decoding candidates, and selecting a most likely decoding candidate from a previously pruned set of candidates. Further, techniques are described herein for generating filler bits (e.g., padding bits, reserved bits, etc.) in a grant message according to a predefined pattern, thereby enabling checking of such bits to further reduce false alarm rates.

    Abstract: A configurable decoder within a receiver (for example, within a wireless communication device) includes numerous decoders. In one mode, the multiple decoders are used to decode different sub-packets of a packet. When one decoder completes decoding the last sub-packet assigned to it of the packet, then that decoder generates a packet done indication. A control circuit receives the packet done indications, and when all the decoders have generated packet done indications then the control circuit initiates an action. In one example, the action is the interrupting of a processor. The processor responds by reading status information from the control circuit, thereby resetting the interrupt. End-of-packet markers are usable to generate packet done indications and to generate EOP interrupts. Similarly, end-of-group markers are usable to generate group done indications and to generate EOG interrupts. The decoder block is configurable to process sub-packets of a packet using either one or multiple decoders.
