Abstract
Quality of service (QoS) is an important task in the design of mobile communication systems. For UMTS system in order to realise a particular service, the QoS requirements in terms of performance and latency, have to be satisfied. Considering the QoS classification according to the priority of latency or performance, possible examples of service scenarios are examined for flat Rayleigh fading channels with emphasis on the turbo decoding algorithm. For rural outdoor operating environment considering SOVA and log-MAP turbo decoding algorithms due to their data-flow similarities, this paper shows that SOVA and log-MAP can be dynamically reconfigured. Particularly, SOVA represents the optimal choice for most of real-time applications, whereas for non-real time applications both algorithms are suitable except for low data rates and small frames where log-MAP is optimum.
