In order to support multi-standard for convolutional coding in wireless communication
and to meet the requirement of high data rate in the future. A radix-4 multi-standard high performance reconfigurable viterbi decoder based on the sliding window pipeline technique with forward traceback algorithm was implemented. The peak throughput of the decoder can reach up to 1.15Gbps@6144bit
600MHz. Compared with the mainstream commercial viterbi decoder
the data processing speed of VCP2 which is proposed by Texas Instruments company is 9.5Mbps@40bit
333MHz
and the data processing speed of viterbi decoder in this paper is 32.173Mbps@40bit
333MHz
performance improved about 3.3 times. In addition
the decoder is superior to other reconfigurable viterbi decoders in area and power consumption. It has great application prospect in the future high data rate convolutional decoding.
