In this paper we present a VHDL implementation of the soft output Viterbi algorithm (SOVA). We discuss the usefulness of the SOVA in a serially concatenated convolutional code (SCCC) system. We explore various hardware design decisions along with their implications. Finally, we compare the simulated performance of the hardware implementation to a software reference model over an additive white Gaussian noise (AWGN) channel for several bit widths and traceback window lengths.Sponsors
