APPARATUS AND METHOD FOR VITERBI DECODING IN SOFTWARE-DEFINED RADIO SYSTEMS

摘要

reconfigurable Viterbi decoder can be programmed to control the reconfigurable data path and the reconfigurable data path Co. and a state machine (finite state machine). Wherein the reconfigurable data path is reconfigurable branch distance (branch metric) computation block and a reconfigurable add-compare- select and path distance is (path metric) composed of a plurality of reconfigurable functional blocks including the calculation block . The programmable finite state machine executes the plurality of context -related commands associated with the reconfigurable Viterbi decoder (context-related instructions).
