ABSTRACT:
An analog Viterbi decoder for decoding an analog signal is provided that includes a plurality of decoding units, provided with a plurality of processing parts each having a plurality of cells arranged to correspond to respective nodes of a trellis diagram, for decoding analog input data using an analog signal processing cell having a circulation type connection structure in which the last processing part is connected to the first processing part; a control unit for performing in parallel a sequential designation of the processing parts with respect to the decoding units; an analog data storage unit including a plurality of capacitors connected in parallel with the processing parts provided in the decoding units; and a first switch unit for storing analog input data in a specific capacitor of the analog data storage units under the control of the control unit. Accordingly, the decoding speed can be remarkably improved.
