In this paper, we study the forced termination probability, blocking probability and throughput of secondary users with practical usage models, which include fixed, truncated exponential, truncated lognormal, truncated Pareto distributions. Moreover, we compare the results of these usage models with the well known exponential distribution model. We consider two system scenarios with/without spectrum...
For original paper see X. Zhu et. al., IEEE Commun. Lett., vol.11, pp.304-6, (2007).This paper discusses a number of errors in the Markov model and analysis of the blocking and forced termination probabilities in a cognitive radio network, given in [4]. The correct expressions of forced termination and blocking probabilities are provided. Under the same conditions as in [4], the probabilities and...
We have developed a dynamic learning and adaptive scheme, named Inverse-Dynamic Adaptive Control (IDAC), for unknown linear dynamic plants. The IDAC scheme provides parallelism, in the sense that the learning and control actions are performed simultaneously [4]. In addition, it provides continuous learning and adaptation capability. In this paper, we extend the IDAC pinciple for unknown higher-order...
