Abstract
SOVA and log-MAP turbo decoding algorithms share common operations. Our analysis shows that the improved reconfigurable SOVA/log-MAP turbo decoder can be implemented in LTE systems for AWGN channel. We examine two data rates, and for each one we consider the nine possible QCIs using five frames. Considering BER and latency limitations for each QCI, SOVA is proposed for most of the cases for low data rates, whereas log-MAP is proposed for higher data rates.
