    摘要: Methods, systems, and devices for outputting of codeword bits for transmission prior to loading all input bits. An example encoder may have multiple encoding branches. The encoder may divide the encoding branches into first and second encoding branch subsets, outputs of the first encoding branch subset being independent of inputs to the second encoding branch subset. The encoder may generate first and second subsets of output bits of a codeword in first and second encoding operations, the generating comprising inputting information bits of an information bit-vector and at least one frozen bit into respective encoding branches of the plurality of encoding branches and generating the first subset of output bits using the first encoding branch subset prior to generating the second subset of output bits using the second encoding branch subset. The encoder may output the first subset of output bits prior to outputting the second subset of output bits.

    摘要: The described techniques relate to improved methods, systems, devices, or apparatuses that support enhanced efficiency in list Viterbi algorithm (LVA) decoding using iterative comparison trellis construction. Iterative comparison may involve comparison and selection from ordered accumulated path metrics associated with feeding transitions by selecting, for each successive rank of an ordered path metrics list for the current stage, the best unselected accumulated path metric of the feeding transitions. The iterative comparison may be performed sequentially for each stage before processing the next stage. Alternatively, the iterative comparison may be pipelined across stages, and different ranks of the ordered path metrics lists for different stages may be concurrently computed in a single trellis search cycle using multiple comparators. Iterative comparison may be used in an inner decoder to generate an ordered path metrics list for processing according to an error checking function using an outer decoder.
