Spectrum aggregation (SA) enables wireless devices to utilize heterogeneous resources, which can potentially fulfill the requirement of broadband services. In this paper, we study the delay-constrained SA, where the characteristics of SA bring various technical challenges. Specifically, the SA capability limitation induces a complicated coupling among the data rate, power and channel allocation, and...
In this paper, the 3-D Markov analytical model for cognitive radio networks of [1] are replaced by out proposed new 2-D Markov analytical model with considerable low complexity to evaluate the performance of Ad-Hoc Cognitive Radio Networks, and the theory mistakes of [1] are corrected. Compared with the existing 3-D Markov analytical model for cognitive radio networks, our approach has achieved the...
