Abstract
A super high speed Viterbi decoder and decoding method with a circularly connected 2-dimensional analog processing cell array. The Viterbi decoder has a 2-dimensional parallel processing structure, in which analog processing cells are located at nodes of a trellis diagram. An output column of the analog processing cells is connected to a decoding column. Thus, the output column becomes a column right before the decoding column. A reference input signal given at a decoding column is propagated to the whole network, while its magnitude is reduced by an amount of an error metric on each branch. The circuit-based decoding is done by adding trigger signals to disconnect the path corresponding to logic 0 (or 1), and by observing its effect at the output column.
