Increase in dfree has been achieved by proposed non-polynomial convolutional coding method. A decoder system (code rate k/n=1/6, constrain length K=4) has been implemented on Xilinx VERTEX-E. Performance of Viterbi decoder with proposed method has been improved from 27% to 75%. High speed (60.299 Mbps) and low bit error rate (BER) are achieved for Viterbi decoder. Proposed Viterbi decoder provides satisfactory probability of error (Ph) performance and high operating speed under conditions including AWGN, co-channel interference and adjacent channel interference environments.Read More
