| Abstract: | On the basis of the Long Term Evolution(LTE) tail-biting convolutional code,this paper introduces the Circular Viterbi Algorithm(CVA) and the Wrap-Around Viterbi Algorithm(WAVA) for this code.Combining their advantages,it makes improvement on the existing algorithms and reduces the decoding computational complexity.The simulation results show that compared with WAVA,the improved algorithm has better performances and reduces the computational amount by 1/4. |
