Y.-S. Chen, C.-J. Chang, F.-C. Ren
2004 IEEE Transactions on Vehicular Technology  
The multirate transmission control problem is modeled as a Markov decision process where the transmission cost is defined in terms of the quality-of-service (QoS) parameters for enhancing spectrum utilization  ...  The state space and memory-storage requirement are then reduced and the convergence property of the -learning algorithm is improved.  ...  ACKNOWLEDGMENT The authors would like to thank the anonymous reviewers for their comments, which improved the correctness and presentation of the paper.  ...
