In the introduction of this paper, we present a background on SDR, in
section 2, we give a quick demonstration of main GSM features and ways to
improve QoS in it. After a short recognition of key fading effects in section
3, we analyze in section
4 the Soft Output Viterbi Algorithm used to
perform equalization tasks in GSM. In sections 5 and 6, we use simulation
results to effectively categorize variable parameters of the flexible equalizer
upon user defined level of QoS. We show also the importance of such
approach in effectively utilizing hardware resources dedicated for
performing digital signal processing tasks, and in reducing power
consumption required for these tasks.
