  • This paper proposes a hybrid spectrum sharing model which combines Overlay with Underlay. Based on the proposed model, considering of perfect and imperfect spectrum sensing, it models the channel activity with discrete-state Markov process. Furthermore, under the criterion of maximizing the system average (ergodic) capacity, it analyzes the power allocation of the hybrid spectrum sharing and deduces the optimal power allocation scheme as well as the maximum achievable capacity of the system. Analysis and simulation results indicate the hybrid spectrum sharing is provided with higher capacity than single Overlay or Underlay system.
