Research and Implementation of Viterbi Decoding in TD-LTE System

摘要：

　　The Viterbi algorithms of the tail biting convolutional code in TD-LTE system is introduced.Aiming at the decoding commons for the convolutional codes of TD-LTE system,this paper presents an implementation program of Viterbi decoding algorithm based on the soft-decision,and validates the algorithm by means of FPGA in the Xinlinxs XC5VSX95T chip,the program simplifies some decoding operations.The simulation result shows that the program has a good feasibility and can meet the decoding requirements.
