HIGH PERFORMANCE VITERBI DECODER SSTRUCTURE WITH 2 DIMENSIONAL ANALOG SIGNAL PROCESSING CELL ARRAY AND MULTIPLEXER and METHOD THEREOF

摘要

A high performance Viterbi decoder structure with a 2-dimensional analog signal processing cell array and a multiplexer and a method thereof are provided to perform high speed decoding by executing hardware decoding using electrical signals. A high performance Viterbi decoder structure includes a 2-dimensional analog signal processing cell array, capacitors(150), and a multiplexer(250). The 2-dimensional analog signal processing cell array includes a mashed analog electronic circuit based on analog signal processing cells(110). The capacitors are implemented as much as the number of stages of the analog signal processing cells so as to store input signals. The multiplexer connects the capacitors to the 2-dimensional analog signal processing cell array based on an input sequence of information stored in the capacitors.
