초록
Soft Output Viterbi Algorithm is modification of Viterbi algorithm to deliver not only the decoded codewords but also a posteriori probability for each bit. This paper presents SOVA decoder which can be used for component decoder of turbo decoder. We used two-step SMU architectures combined with systolic array traceback methods to reduce the complexity of the design. We followed the specification of CDMA2000 system for SOVA decoder design.
