摘要：
A branch metric duplication method substantially reduces interconnection delays. The branch metric duplication method is particularly useful to implement a high speed radix-4 Viterbi decoder targeted for FPGA applications. The decoder includes a plurality of branch metric computation units (BMCUs), at least one add-compare-select unit (ACSU) having a plurality of cells, and a survivor path memory unit (SMU). The plurality of BMCUs, the at least one ACSU, and the SMU are configured to implement the decoder.
