In this work we study an adaptable SOVA/log-MAP turbo decoder for LTE mobile standard and flat Rayleigh fading channel. Particularly, this decoder is shown to adapt dynamically to different service scenarios, considering parameters like performance and complexity for indoor/low range outdoor operating environment (mobile speed of 4 km/h). We concentrate on physical shared channel and use pipeline turbo decoder architecture with 12 iterations. We examine two low data rates and for each one we consider the nine possible QCIs using five frame lengths. Considering BER and delay limitations for each QCI, SOVA is proposed for most of the cases for 0.5 Mbps, while either algorithm can be used for 10 Mbps and QCIs with tight BER limit. © 2015 IEEE.
