Abstract

Dynamic spectrum sharing problem (QADSS) under QoS constraints in TDMA-based MIMO Ad Hoc network is investigated. Using a stochastic approximation approach, an on-line recursive scheme is derived to be capable of learning the underlying channel distribution dynamically. A simple yet optimal algorithm via primal and dual decomposition is further employed to solve the constrained utility maximization problem formulated. Numerical results demonstrate that the proposed online algorithm converges to the optimal solution from arbitrary initial values.
