On the basis of the tailbiting convolutional code for Long Term Evolution(LTE) systems
this paper chooses an optimal Viterbi decoding algorithm for the TD-LTE test system after comparing multiple Viterbi algorithms by simulation and realizes it in the TMS320C64x DSP.It presents a number of specific strategies and techniques for software optimization and greatly simplifies the addition comparison selection butterfly computations.The running results of the decoding program in CCS3.3 verify the feasibility and effectiveness of this algorithm and the optimization strategies and techniques.
