摘要：

In　modern　times,　people　usually　use　channel　coding　technology　to　ensure　the　effectiveness　and　reliability　of　information　transmission.　As　a　better　coding　method,　convolutional　coding　is　widely　used　in　wireless　communication　standards　such　as　GSM,　cdma20000　and　IS-95.　This　paper　introduces　the　coding　principle　of　convolutional　code,　uses　Viterbi　decoding,　and　verifies　the　performance　of　convolutional　code　through　MATLAB　simulation.　Simulations　have　found　that　when　the　bitrate　is　1/2,　the　performance　of　the　convolutional　encoding　increases　with　the　length　of　the　constraint.　And　in　the　decoding　phase,　the　soft　judgment　Viterbi　algorithm　due　to　the　hard　judgment.　©　2022　SPIE.
