In this paper, we consider a time-slotted energy harvesting (EH) cognitive radio (CR) network, where the secondary user (SU) is powered by a continual source of energy harvested from ambient environment. Jointly considering the primary user activity on the primary channel, diversity of channel conditions, energy replenishment process as well as the imperfection of spectrum sensing, the SU aims to...
The problem of channel quality prediction in cognitive radio networks is investigated in this paper. First, the spectrum sensing process is modeled as a Non-Stationary Hidden Markov Model (NSHMM), which captures the fact that the channel state transition probability is a function of the time interval the primary user has stayed in the current state. Then the model parameters, which carry the information...
