Abstract: In an embodiment, a source device encodes source information corresponding to a frame, assembles an initial data frame that includes the encoded data blocks, and transmits the initial data frame to a destination device. The destination device decodes the encoded data blocks and assembles a restored version of the initial data frame. The destination device identifies corrupted data blocks and uncorrupted data blocks within the restored version, stores the uncorrupted data blocks, generates a message that identifies the corrupted data blocks, and transmits the message to the source device. In response, the source device encodes source information corresponding to the corrupted data blocks identified in the message, assembles a responsive data frame, and transmits the responsive data frame to the destination device. The destination device produces a corrected data frame from the retransmitted data blocks and the previously-stored uncorrupted data blocks.

Abstract: Embodiments of a decoder and method of decoding blocks of soft bits in a wireless receiver are generally described herein. Other embodiments may be described and claimed. In some embodiments, a memory is initialized with encoded input data and updated with sums of extrinsic reliabilities. Decoded output data is provided from the memory after a predetermined number of iterations.

Abstract: Embodiments of a system and method for signal processing in a wireless communication device are generally described herein. Other embodiments may be described and claimed. In some embodiments, the wireless communication device comprises a first reconfigurable processing engine for configuration by a processing unit to perform a plurality of baseband processing operations on baseband samples. The processing unit may reconfigure the first reconfigurable processing engine for performing each of the plurality of baseband processing operations after completion of a prior one of the baseband processing operations. A second reconfigurable processing engine for configuration by the processing unit may perform decoding operations on output data generated by the first reconfigurable processing engine.

Abstract: Apparatus and systems, as well as methods and articles, may operate to buffer a state of an iterative decoder operating on a codeword associated with a partially decoded forward error correction-encoded data block, and to restore the state to perform additional decoding iterations on the block during a period when the decoder is idle.
